Crash

When trying to play any of my worlds the world would load for 5-10 seconds then it would crash back to the xbox home screen.  I have gone through the recommended troubleshooting, removed the worlds from local storage and resynced with microsoft, signing out of my microsoft account and signing back in then resyncing with microsoft again, at this point none of my worlds will load at all, I receive an error that the world is not fully synced and cannot be played.
