After opening minecraft bedrock, I see Mojang logo, then black screen, then white and minecraft closes itself. I don't even see loading screen.

Backstory: This week I joined beta testing to see 1.16 and had the same problem, but i fixed it changing beta testing to beta testing rtx and back to normal beta testing. Same day I wanted to play on 1.14, but I had problem with leaving it. In Xbox Insiders was written that Im unerolled from beta testing, but after reinstlling minecraft I still was in beta testing. Next day I got notification that this bug is fixed, so I reinstalled minecraft and I have this problem again.

How I tried to fix it: Reinstalling minecraft - doesn't help, ending task for runtime broker - doesn't help.
