this bug started to appear since 1.15

I can't switch accounts, and I also can't change skin in multiplayer game

I fall out of the game when I go to another open

Not yet resolved

When I try to sign in to Xbox live Minecraft simply closes, I've tried several times and nothing

It is taking too long to enter the realms, in the previous version it was not like that, and when it finally enters, the game simply turns white and there is no way to do anything but close it

the button "[...]" to open the inventory has a very harmful bug, if clicked twice in a row the game closes, please fix it!

I can't see messages from other players except my added friend, I've seen everything in the account but nothing has resolved
