Hi,
It seems the account is locked out and can you follow the process listed here please - common-problems-with-two-step-verification-for-a-work-or-school-account-63acbb9b-16a1-47b9-8619-6a865e8071a5
Also if none of the steps fix the issue I will suggest you to log a call and reset the MFA for your account by using this link - contactus
