Hello Mojang! There is a bug with my downloaded Minecraft 1.16, that is showing a Red loading screen with a sign ,, MOJANG studios" and it doesn't load, even if I wait an hour, it's still showing this screen. Unfortunately I don't have a Microsoft account if you need it for more information. Please help!
