Issue generating standard API Key: Receiving restricted "AQ." token instead of "AIza"

Hi Google AI Support Team,

I am currently encountering a system restriction preventing me from generating a standard API key on Google AI Studio.

I am building a personal Java web development project for self-study and need to integrate the Gemini API. However, whenever I try to generate a new API key, the system only outputs a restricted token starting with "AQ." instead of the standard "AIza..." format.

Because of this, my Java application cannot authenticate and throws the ACCESS_TOKEN_TYPE_UNSUPPORTED error when making HTTP requests to the Gemini endpoints.

Could you please review my account and help remove this restriction so I can generate a standard API key and continue my personal learning project?

Thank you for your time and support!

Best regards, Nhat
