i joined the beta then i unjoined and now i can't play minecraft 1.13

1.13 sucks, one of the if not the buggiest update to MCPE.  It won't load anymore at all.  I joined the beta 1.14 on my other xbox with the same account, then i unjoined on my main xbox and then reinstalled it multiple times, and now it won't launch anymore.  PLEASE FIX 1.13
