With a wide release across Windows 10 (PC), PlayStation 4, Xbox One, PlayStation 5, Xbox Series S, and Xbox Series X, users around the globe are now getting their hands on the new first-person shooter video game. Like any newly released game or update, many users are now encountering some problems and bug issues inside Black Ops Cold War.

A bunch of users are shown the “Umbrella merge conflict” error on their screens when players try to enter a multiplayer game. The issue is believed to involve your connection to the game lobby’s servers which isn’t able to re-establish a connection.

To fix this issue, it’s recommended that you restart your game and you should be good to go. In case that doesn’t fix your problem, you will have to wait for the game’s developers to roll out an update if the issue appears to be widespread. This is to be expected if you’re an early-bird customer of any game or application as there will be bugs and issues in the very first version but rest assured that those will be ironed out in future releases.

“Yorker 43 Good Wolf” error

Right after loading the game, many users are being greeted by the “Yorker 43 Good Wolf” error on their screens. The issue seems to revolve around the inability of the game to connect to its servers which is evident from the fact that it takes a long time for the game to move from the “Connection connecting to Call of Duty services” screen to the game’s loading screen.

As it turns out, the fix for this has been established since the game was first released in beta as it was also reported at the time. We’ve already prepared the following guide that lets you get past the “Connecting to Call of Duty services” screen when you face this error. You can read in the link below.

Error code: 3107840166

While some are encountering issues right after loading the game, a certain section of users is facing problems when they’re creating their personal profile within Black Ops Cold War. The issue labeled ‘Error code: 3107840166’ seems to be widespread and oddly enough, it appears during in-game scenes and not when the game is loading.

Error Code: 3107840166 from blackopscoldwar

According to what the commenters have to say in this Reddit post, it appears as if this problem has something to do with certain AMD Ryzen processors. We believe so because most of the people reporting the issue happen to run the game in Ryzen-based hardware. If that’s the case, the issue might also be prevalent in the new generation PS5 and Xbox Series X consoles as well.

At the moment, there’s no fix or workaround that lets you dodge Error code: 3107840166 when playing Call of Duty: Black Ops Cold War but we’ll make sure we update this section once there’s an update that patches the error in the future.

“Referral denied” error

Many Playstation owners have been left with the inability to get their hands on the Call of Duty: Black Ops Cold War and are instead getting the “Referral denied” when accessing the PlayStation Direct website.

The problem doesn’t seem to be related to just the Call of Duty: Black Ops Cold War game as those visiting the store for other reasons are also redirected to a blank page. This blank page when refreshed reads “Referral Denied” saying you don’t have permission to access the webpage.

We don’t know why users are facing the issue at the moment but we’ll make sure we update this section once there’s some good news.

Split-screen mode issues

Call of Duty: Black Ops Cold War lets you play in a split-screen mode to play the game locally with others around you. With this mode, you and your friends can take advantage of your local game setup to play multiplayer matches without needing to log in to another console.

Sadly for many, Split-screen has been giving a slew of issues for different players. Firstly, if the option works for some, players are experiencing frequent lag and game crashes when split-screen is enabled. There are also a bunch of instances where players aren’t able to completely see some elements that they should otherwise be seeing in split-screen.

Now THIS is black ops cold war’s split screen. from blackopscoldwar

But a lot of the people are just complaining that Split-screen just doesn’t work on their console. For instance, the option doesn’t seem to appear for some Xbox Series X users while some others aren’t able to switch it ON even if it appears in the game lobby screen, especially in Zombies mode.

The game’s developer hasn’t yet rolled out a fix for the problem but we can expect the issues to get resolved in any future update after the current version 1.04 of the game.

Game keeps crashing in multiplayer mode

For some of the players, the Black Ops Cold War seems to crash the moment multiplayer mode is selected on their PC version. When a player clicks on the multiplayer mode, you’re taken to a cutscene and when your try to exit that, the game crashes with a Fatal error that reads “Unfortunately, the application has unexpectedly stopped working”.

Fortunately, the Reddit user who had posted the issue also provided a solution which involved moving some game files from the beta to the public version of the game and then deleting the beta folder once and for all. You can read the solution down below.

“Connection to Blizzard game servers lost” error

Another issue that’s happening for PC players of the Black Ops Cold War is the random “Connection to Blizzard game servers lost” error. The error appears to be because of the inability to connect to the game’s servers which means players can’t even get past the game’s loading screen preventing them from selecting any of the campaign modes.

Fortunately, there’s a workaround that temporarily solves this issue. To get it resolved, you need to launch Blizzard, head over to ‘Options’, and select ‘Show in Explorer’ for Black Ops Cold war.

When the Explorer opens with the game’s location, right-click on the “BlackOpsColdWar.exe” file and click on ‘Properties’. Inside the ‘Properties’ window, select the ‘Compatibility’ tab and check the box adjacent to ‘Run as Admin’, and click on the ‘Apply’ button at the bottom.

UI error 80184

The UI error 80184 appears for Black Ops Cold War players who are trying to play multiplayer games with their friends. The issue appears when a user is trying to log in to their account which never successfully gets past the login screen and players are instead forced to restart the game.

The issue can be resolved if you open the game using the second account and also make sure that this account is fully set up and verified.

UI error 26484

Some Playstation players of Black Ops Cold War are being displayed with a UI Error 26484 on their screens after installing the game’s latest update on their consoles. The error prevents users from sending invites to their friends, thus keeping them from playing a multiplayer match.

Any other PS4 players unable to send invites? from blackopscoldwar

The issue appears to be happening in both current and older generations of Playstation consoles with both PS5 and PS4 players struggling to get past the error code.

While Sony or the game’s developers are yet to acknowledge the issue, some have found a solution that temporarily fixes the problem. Instead of sending invites within the game, you can go to your friend’s profile on the Playstation home screen, and join their session if it says that they’re playing Black Ops Cold War.

Another workaround to play multiplayer matches is to join each others’ joinable parties or matches which you can do by pressing the Triangle key on your controller for sending invites.

UI error 100002

Of all the errors that have been showing up on users’ screens, the UI error 100002 would most definitely be the one that many have been welcome with. This particular error seems to be common in console versions of the game as it crashes mid-game when a user is in a multiplayer match and is forced to restart the game to get it resolved.

Black Ops Cold War is a scam and extremely broken! from blackopscoldwar

Other users have commented on this post saying they get the same update and are forced out of the game and back on to the console’s home screen when the error occurs. Judging by the time of these complaints, it appears as if this error started appearing after the latest update, as is pointed out by some of the users in the comments.

UI error 86494

Cold War users are getting the UI error 86494 flashed on their screens and from what it looks like, the error shows up when the player is inviting friends for multiplayer-gaming. The problem seems to be quite widespread with some players getting stuck on the multiplayer startup screen and then failing to load up a match with their friends logged in.

Black Ops Cold War UI Error 86494 from blackopscoldwar

Somehow the problem seems to be happening for Xbox and Playstation users as well, meaning this could be a cross-play-centric problem and it requires the developers to roll out a patch to get the game to work again.

UI Error 70745

A few people who purchased Cold War are reporting a UI Error 70745 that keeps popping up every few seconds. Although the error can be dismissed, it pops up repeatedly and even freezes the users’ screens for a second, thus rendering the game practically unplayable.

UI Error 70745 from blackopscoldwar

Users who are complaining of the same issue have seemed to find no way to make it work even after re-installing the game on their PC and scanning/repairing the files.

Fortunately, another player has pointed out that the issue has something to do with key binds ‘[‘ and ‘]’. Those who have either of these keys enabled while playing the game will have to replace the key combinations or remove the ones mentioned here.

As it turns out, the issue is happening for those who changed their default key binds to interact with an in-game object from ‘F’ to ‘[‘ or ‘]’, and switching back to the default key input solves the problem.

UI Error 66146

Several PC players of Black Ops Cold War are being greeted with UI Error 66146 which makes their game run really slowly, with some complaining that the game’s frame rate stands at 1 FPS because of the error. Other commenters on this Reddit post also appear to be experiencing the same issue in addition to losing parts of elements that should otherwise be visible on the screen.

Delete files from Black Ops Cold War Beta version

For those of you who first played the Cold War Beta game before the public release, a lot of your issues might be prevalent due to the existing beta files that are still available on your PC.

If you’re one of those who tried out the beta version of the Black Ops Cold War, then you must locate the game on your storage and uninstall the beta version of the game. If you can’t delete all the files that are associated or packed inside the game’s beta folder.

Sometimes, an app might not be included in the trusted apps list just because it is relatively new.

On this screen, click on ‘Add an allowed app’, select the “BlackOpsColdWar.exe” file.

Hide all Microsoft services inside MSConfig

Some users are pointing out that the Cold War PC version is crashing to the desktop without showing any error code. It’s believed that the issue has something to do with services that conflict with anti-cheat software, noise software, VPN apps, or a cheat engine opened in the background.
