I can't login to Minecraft, why?

Hi thanks for helping me.

I lost the account it has been hacked and i can't login with my own email. I have the transaction email from minecraft in my mail but i can't login on that account anymore

I have the same problem and it's exactly the same on the phone. I put my Microsoft credentials, the login window closes normally. then this error appears. I can't login to the minecraft launcher either

P.S. my password was not made phonenumber.

新しくマイクロソフトアカウントを作りなおしたらセーブデータを消さなくてもログイン出来ました！

再度フレンド登録をしなければいけませんがストアで有料な物を購入してなければこれがオススメです。

[Translation-When I re-created my new Microsoft account, I was able to log in without having to erase the save game! I have to register as a friend again, but this is recommended if I do not purchase a paid thing in the store.]

It's not in the migration instructions, but after the migration, you have to ADD a NEW account, and link it to your Microsoft account. Startup will take longer, but it sure works.

On the login prompt in the java launcher, go back. You'll see the mojang account you had been signing into - ignore it, and add a new account to the launcher. Using the email address associated with the microsoft account you just migrated to, sign in with the email address and password of your microsoft account. It's not an elegant migration on the UX side of things, but it does work.
