I cannot log in my E5 account

I have an E5 subscription. One day, I accidentally deleted Authenticator’s verification account on my phone. I found out that without any verification device, the login interface still requires me to open Authenticator for verification, but I can’t verify it because I don’t have any device to do it. Verification, there is no administrator in my organization who can cancel the MFA session for me or disable multi-factor authentication for me, how to solve it?
I'm Chinese so I cannot type English very well, sorry.
