Modern Warfare 2 Beta Keeps Crashing Error CE-34878-0

If you are currently unable to play the MW2 beta on your PS4 due to the CE-34878-0 error message, you should know that you are far from being the only one. A number of players are currently reporting the same problem. And they are all exclusively appearing on the PS4 version of the Modern Warfare 2 Beta. Some players state that MW2 crashes after they finish a match. Others report that MW2 beta crashing occurs while a TDM is loading. The CE-34878-0 error comes with a message that says: “An error has occurred in the following application. Call of Duty: Modern Warfare II Beta”.

So, is there a solution to fix the CE-34878-0 error to stop Modern Warfare 2 Beta crashes? Unfortunately, we are currently not aware of any 100% workable fixes. The game has just been released in the beta, and some bugs and glitches are bound to happen. And that’s particularly the case with the previous-gen versions (PS4 and Xbox One) of the game. The game is being made primarily for the current-gen consoles, and the old-gen port is not a priority. The developers are already pushing the limits of what these almost-10-years-old consoles are able to do.

If some workaround solutions pop up in the meantime, we will make sure to update the article. The only currently proposed solution, shared by Reddit user psn1453, says that you could try with a PS4 database rebuild. But a fair warning – expect more of similar problems on the old-gen version of the game, especially during the beta period this September. For now, that’s all we can say about the “Modern Warfare 2 Beta Crashing Error CE-34878-0” issue.

    Mine is stating server is not available, this happens always on the Playstation release and then gets worked out by the time all the others are on there. Not fair to us to have a private beta that doesnt work;.

    On ps5 as soon as I hit find match it says unable to join server, error cause 10, error code 2004. This is BS pay for the vault edition to get early access and can’t even enjoy it. Why did I spend the money…

    I’m on PS5 and I’m having no issues playing the game, the only issue I’m having is that it won’t let me gain any experience past lvl 15
