"Question
I’m getting stuck on a loading screen every time I choose Single Player or Multiplayer from the Main Menu. What can I do?
Answer
Delete the Game Options file and reboot the console.
A small number of players may be experiencing this hang when loading into Single-Player and Multiplayer even after clearing the cache and reinstalling the latest title update. Deleting the Game Options file has often fixed the issue.
