Google AI Studio access denied for Austrian account despite region being supported

Hello,

I am unable to access Google AI Studio with my Google account, even though Austria is listed as a supported region. When I log in, I am automatically redirected to the “Available Regions” page.

All account information is complete: date of birth, gender, and address are confirmed. The account is in good standing.

A second personal Google account, accessed from the exact same device and IP address in Austria, has full access to Google AI Studio without issues. This confirms the problem is account-specific, not regional.

Could you please investigate why this account is blocked from accessing Google AI Studio and advise on how to resolve this?

Thank you.
