can't access my Minecraft account because of Microsoft account

i haven't played minecraft for a while so the launcher asked me to log in using microsoft account but after i did that the launcher just created a new account. the account with purchased minecraft has the nickname "". i tried using my phone instead of email, but it just logged in to microsoft account again. i migrated my mojang account on february 9 2022 and played on it after that before encountering this issue. please tell me what should i do to regain access to my original account?

:)
