I’m hoping to get some more eyes on this issue. Maybe someone here knows who to send this to.

The issue: Black ops 3 zombies now crashes consistently in zombies. This started happening randomly toward the end of October. There are different ways to trigger this.

• Load a custom map in a private match, a solo game, or offline load. It crashes on the forest loading screen.

• Start a non-custom map in solo or private match while online and end the game or die. The game will crash when loading back to the main menu, again on the forest loading screen.

• Load any non-custom map in offline mode, the game will crash while on the opening cutscene.

This has been tested on the latest steamOS stable, beta, and preview with no change. Playing this game on Windows has no issue so it is Linux/proton specific.

This has also been tested with proton 7, 8, experimental, and ge proton.

According to SteamDB, this game was last updated on July 19th 2023. That tells me this was not caused by any game update.

Edit: I also want to mention that if someone hosts a game on windows, you can join them just fine but the game crashes when it ends just like it does in the scenario above.

Edit 2: If you set up the boiii client (a third party client) it will fix this issue but it replaces the online service with its own deal so you can’t play using the Steam service so it’s not ideal. It is a last resort for people who only want to play offline really as my buddy and couldn’t figure out how to join each other through this.

If anyone knows someone that could look at this or possibly has a fix, it would be greatly appreciated. This is not the first post about this here and I’ve also seen it discussed on r/steamdeck.
