Call of Duty: Warzone and Modern Warfare players have been hit by the “unknown function” Fatal Error code which is preventing them from joining a match or even launching the game in some cases.

Warzone’s 80s Action Heroes event officially concluded with the June 3 update. This closed the Nakatomi Plaza vault, provided bug fixes, and gave a small buff to the PPSH-41. However, this update appears to be causing an error code, with players reporting they can’t join matches or even launch the game in some cases.

Since the June 3 update, several players have been hit by the “unknown function” Fatal Error code. Players across Xbox, PlayStation, and PC are met with this code either when booting up Modern Warfare/Warzone, or when trying to queue into a game – even a Private Match.

This Fatal Error crashes the whole game, completely stopping users from playing either Modern Warfare or Warzone. One player has reported that single-player still works, but with Season 3 wrapping up soon and Season 4 on the horizon, players will want to keep grinding to finish the Battle Pass.

There have been a ton of Reddit posts on the topic since June 3, with many players reporting that they can’t access the game. Judging from the Reddit posts, it seems to be hitting new players the worst, with many getting hit by the code in the Warzone training mode.

Affected players have tried a variety of methods such as running the game in safe mode, doing a scan and repair, rolling back graphics drivers, fully uninstalling and reinstalling, and signing out and back in. None of these methods are reported to have worked, so contacting Activision support appears to be the only proven solution.

“Our intel cannot explain the origin of these mysterious red doors around Verdansk, but one thing is certain: They allow you to [[REDACTED]] around the [[REDACTED]]. What’s behind them? Explore and enter them to [[REDACTED]] across the [[REDACTED]].
