Crashing on start-up. (Better Together Beta)

For the past several weeks when I try to launch the Better Together Beta on Xbox One, it freezes on the Mojang screen for a few seconds, then crashes and pops up with an error message telling me to reset my console. I've reset, uninstalled, reinstalled, basically everything I can think to do. The only thing that works is if I unenroll from the beta, uninstall it, reset my Xbox, reinroll, and reinstall. After that I can play the game, but its a few updates behind meaning I can't play with my friends on Windows 10.
