Created an Entra ID Tenant yesterday but cannot access it due to token errors

Yesterday I created an Entra ID tenant during the outage that happened apparently, and when I am attempting to sign-in I get constant pop-up errors related to token authentication. I've tried resetting the browser and also from an incognito window. If I click the "sign-in again" button, my account isn't recognized in the tenant. See the attached errors

How can I fix this?

The account needs to be added as an external user in the tenant first. Sign out and sign in again with a different Azure Active Directory user account.
