It wouldn’t be a Call of Duty game without persistent bugs that stop you from being able to play. In Modern Warfare 2, there have been dozens of bugs and errors that have prevented players from enjoying a session of multiplayer. Recently, a new error code has popped up that is seemingly specific to consoles.
The error, which reads “Lobby Not Found Error Cause: 10,” apparently started appearing on all of the major consoles after a recent update, being specific to the PlayStation 4 and 5 and Xbox One and Series X|S. Players have also reported that only multiplayer is affected, so Warzone 2 and DMZ players should be safe.
