Why can't i use Minecraft Java Edition on my microsoft account? i already have the game, and i can't play the game after migrating. and when i try to install the Minecraft for Windows, it wont install and say "error" @MojangSupport

are you trying to log into the launcher with your microsoft account? after i had migrated accounts i was still trying to log in with my mojang account for about half an hour lol

I already logged in using my Microsoft account, its just that i cannot play the java version. I even tried the Minecraft for Windows Edition and i could not install it.
