Error Code 264 Entering Superstar

Trying to play superstar but keep getting error code 264 I believe. I’ve tried everything I could find on google recommended to fix it. Went through support too and tried everything they said to fix it and kept getting the same error message. They recommended I post on the forum to get something done about it which makes no sense. Really frustrating with how much money we spend to play these games and there’s always issues.
