Can't sign into my account. 2FA codes not working and resetting them not working

Question

I am unable to access my development account. Every time I use the code that should normally work on the authenticator, it doesn't work. I can log in as an owner of the subscription and try to resell it, but it makes no difference. I tried to revoke the two-factor authentication. I tried to reset the password. I'm currently unable in any way to log in with this account. Please tell me what I need to do because this is business critical.

I have the correct password, I have access to my email, so I can get email codes, but it still asks me for authentication codes, and I'm in no way able to reset them or redo them or connect up a new phone number.
