I am having the exact same problem. Have you been able to find a solution? I can not get access to anything as I am stuck in this loop. I click sing in another way and it still wants the authenticator app or the code from the app - which is not linked to the account! And I can not link it to the account unless I have the authenticator app. This is nutty! I too am my own Microsft ADMIN but I can not log in because of the loop.
