Agents League Hackathon – Innovation Studio Activation Blocked

I am registered for the Agents League Hackathon, but I am entirely locked out of the Innovation Studio portal due to an Entra ID tenant syncing issue.

When I click the "Activate Your Profile" link from the welcome email, I receive the following error:

AADSTS500200: User account '******@gmail.com' is a personal Microsoft account. Personal Microsoft accounts are not supported for this application unless explicitly invited to an organization.

I have already attempted the standard workarounds:

Opening the activation link in an Incognito/Private window.

Completing the email-code verification loop.

Both still kick me back to the same AADSTS500200 error. It appears my email address was never successfully provisioned as a Guest User in your backend Entra ID tenant, so the firewall is blocking my personal account.

Could an admin please manually sync my email (******@gmail.com) as a guest in the directory and push a fresh invitation link to my inbox so I can submit my project before the deadline?
