This week I had problem with leaving minecraft beta tests, beacuse I wanted to play with friends on 1.14. When problem was fixed, I unistalled Minecraft and installed it. After opening minecraft I see Mojang logo, then black screen, then white and minecraft closes itself. Also before joining minecraft beta I had the same problem, but it fixed itself when I changed minecraft beta to minecraft beta rtx and then to normal minecraft beta. I tried reinstalling it and ending task for RuntimeBroker.exe but nothing help.

Second bug: when I uninstall minecarft I still have minecraft on desktop and when I open it, minecraft opens even when minecraft is uninstalled and after closing it I see minecraft in applications and I can uninstall it again
