Infinite Authenticator Loop

I can't login to TWO of my emails I need for my non-profit. All of the emails were created a while back and are transferred over whenever the governing board changes. I have both the admin email and a general member email. I am logged onto Outlook for the general email only on my phone. Every single time i try logging onto either email it tells me to authenticate with Microsoft authenticator. The thing is, I AM TRYING TO LOG ON TO MICROSOFT AUTHENTICATOR. I don't have the code, and there is no other way to sign in. All roads lead to Microsoft authenticator. i can't sign in or approve any sign ins and I'm stuck in an infinite loop. I have spent over 15 hours trying to login because I sorta have to in order to do the work I need, and there is no phone number or person to contact. Everything is with AI and help forms that do NOTHING. This is beyond frustrating. Microsoft, considering you're a billion dollar company this is so stupid and I have never encountered something so beyond dumb and infuriating. I can't even contact my admin or help-desk because I don't know who the admin is (it might be me but guess what I CANT LOG ON TO THE ACCOUNT EVEN IF I WANTED TO). Help me please. I have lost all hope and I have zero clue what to do.
