How To Fix Warzone Fatal Error: Unknown Function
- Check that the Warzone version you are playing is the most recent. We know this is what users always hear, but it works a lot of the time, so do try it.
- Restart your console or PC and try to relaunch the game. Again, this is cliché, but that's for a reason - these steps will often resolve the problem.
- Delete and re-download the entire game. Many users have been able to play since the update, so you might be able to install the latest version without error if you start from a clean install.
- Reddit user u/Quale51k suggested signing out of your Activision account and signing back in. One user on Xbox reported this working, but others on PlayStation and PC said it did not resolve the problem.
We really hope these fixes worked, nothing infuriates us as much as a bug in Warzone, especially just as the Weekend begins. If none of these steps worked out for you, don't worry: Raven regularly releases patches, and should fix Warzone Fatal Error: Unknown Function with a patch someday soon.
