Error 500121 in Microsoft Authenticator usually means that the system has rejected the sign-in due to a mismatch in MFA. Which method of MFA u using?
one more - I just check the link https://login.microsoftonline.com/common/debugmode (what u give) the AADSTS900561 error in Azure Active Directory (AAD) usually means that the sign-in is blocked due to incorrect configuration or a mismatch in authentication parameters. just add to that my comment - check Conditional Access Policies to ensure sign-in is not blocked. Verify that the authentication method matches the allowed settings. Try signing in at https://myaccount.microsoft.com to check for additional authentication prompts. Admins should review Azure AD Sign-in logs for more details. Also, check Azure Status for possible service outages (not really could be... but just in case for 100% be sure).
