Blocked by error AADSTS16000 when trying to access Azure Portal support after academic verification

Hello Microsoft Support Team,

I recently completed my academic status verification successfully through the GitHub Student Developer Pack and Microsoft academic verification portal. However, the final step of creating the Azure for Students subscription failed with a generic verification error screen.

When I try to sign in to the Azure Portal to open a billing/subscription support ticket as instructed, my personal Microsoft account is blocked by error AADSTS16000 (stating that the user account from identity provider live.com does not exist in tenant Microsoft Services).

Because of this tenant loop, I have no way to submit a support ticket from inside the portal. Could a Microsoft Moderator please reach out to me via Private Message so I can safely share my correlation/session details for a backend account check?

Thank you very much!
