When 1.14.30 was released on February 11, 2020 Minecraft won't open. Click to open goes to Mojang white screen and shuts down. All within 5 seconds. I have not been able to play it since. And no new bug fix has come out since 1.14.30 hotfix (bug fix). Please fix this! 

Update 3/30/20- The Cloud saves your game files as long as you are connected to Xbox live It'll sync. So uninstall game, power cycle Xbox, then reinstall.
