Google AI Studio account blocked — “Failed to list models: permission denied” despite verified age

Hello Google AI Studio team,

Google AI Studio previously worked normally on my account, but now the web interface opens and immediately shows:

“Failed to list models: permission denied. Please try again.”

I have already verified the following:

  • Personal Google account
  • DOB is 1990
  • Google age verification says no additional verification is required
  • Google AI Pro is active
  • Tested in Chrome Incognito with only this account signed in
  • The same error persists

Google One Support reviewed the issue and referred me to Google Cloud.
Google One Case ID: 9-81760000****

Google Cloud Basic Support then redirected me to community support.

AI Studio previously worked on this exact account, so this appears to be an account-level eligibility / region / security restriction.

Could a Google AI Studio team member please review the account status or tell me how I can submit the affected account privately for manual review?

I can provide screenshots and my Google Account email via private message.
