I am the sole admin of the B2C tenant and deleted the account on my authenticator. Can't login anymore in the tenant to enfore re-enroll MFA.

Thanks for sharing requested details in
Private messagestab.The issue pertains to a tenant lockout, where no other global admin in the tenant has the necessary permissions to login and make changes in your tenant.
To resolve this, we have engaged our Data Protection team through a support ticket. They will reach out to you via email or phone to help restore access to the tenant and assist in resolving the issue.
