Founders Hub login loop + "This account can't be used for Microsoft for Startups credits" (eligible personal MSA)

I'm a founder enrolled in Microsoft for Startups Founders Hub. Earlier today I successfully signed up and reached the Founders Hub dashboard (welcome screen) using my personal Microsoft account ******@getnema.app.

Now I cannot access it anymore:

1. The Founders Hub portal (foundershub.startups.microsoft.com) keeps looping back to the sign-in screen.
2. When I reach the Azure for Startups view and try to unlock the $1,000 Azure credit, it shows: "This account can't be used for Microsoft for Startups credits. Sign in with an eligible Microsoft account to access this offer."
3. Selecting the work/school variant of my email gives: "The selected user account does not exist in tenant 'Microsoft Services'..."

I have verified the following:

• I am using the correct account, ******@getnema.app, as a PERSONAL Microsoft Account (it signs in successfully at login.live.com and shows "My Microsoft account").
• There is no alternate directory to switch to (Switch directory shows none).
• I tried incognito mode and fully cleared cookies — the loop persists.

My account appears stuck in a broken onboarding/provisioning state. Could you please reset / re-provision my Founders Hub membership for ******@getnema.app so I can unlock and activate the Azure startup credits?
