I cant play minecraft, because of login errors

ok, but the issue is not your migration to Microsoft 365, this is because you migrated your Minecraft account, to a Microsoft account, and the error on the first screenshot is because you are trying to use the Mojang login still instead of the Microsoft login option at the top of that box

This of minecraft when i login in minecraft it shows the error i told you

does any1 know how i can login and just play my game offline, because my savegame is on my xbox live account i dont know how to start my savegame offline mode now, it requires me to login in the xlive account wich i cant coz error code.... som1 know how
to play offline only with a xlive account?

Hello. I already changed my password twice. The problem i am having is that around 2-3 years ago i bought Minecraft and have been playing it but all of a sudden it says my account doesn't have it and its not showing up in my purchases. Recently I wasn't able to login with my microsoft account because it says it doesn't have it anymore. I think the account got hacked and changed. Please get my Minecraft back. I already contacted Minecraft and they said i have to contact microsoft. My minecraft username is ajisuppose. Also my Xbox username also changed and i cant login anymore. I can only play bedrock. Thank you.

Currently if I try to login to minecraft it gives me the error code 0x80048820, it still shows my old Account name tho, so it might be because this account is somehow gone.
