I recently experienced the same issue. The game froze while attempting to save, I force-quit the game through the xbox home screen, and now the game is stuck attempting to fetch profile data. The issue persisted when I disconnected from the internet. I haven't attempted to uninstall/reinstall, but I'll try that next.
Has anyone been able to find a fix? From the other forum it sounds like the OP was able to correct the issue by deleting locally saved data, but I don't have any saved data for this game on the xbox. Happy to post on that thread if it will get more eyes - this one seemed more active.
