What is the 30005 error code in MultiVersus?
This error is a bug that seems to be related to the game’s in-built anti-cheat system also known as Easy-Anti Cheat, to help stop players from cheating in the game. But if one of the game files has become corrupted, the Easy Anti-Cheat service is having issues, or perhaps your game is not updated to the latest version, then this could cause the 30005 error you are receiving.
