Google AI Studio browser access denied: "Permission denied"

Hello,
I am having a problem accessing Google AI Studio through the web browser.
My goal is simply to use Google AI Studio in the browser. I do not need to use the Gemini API or an API key.
However, I am receiving a “Permission denied” error when trying to use AI Studio.
I have already tried the following troubleshooting steps:

Verified my age

Signed out and signed in again

Cleared browser cache and cookies

Used Microsoft Edge Guest mode

Tried different browser conditions

Checked my Google account settings

Contacted Google One Support
I also contacted a Google One support agent. However, the agent could only provide general help pages and was unable to investigate the Google AI Studio access problem.
I also tried generating an API key only as a troubleshooting step. When I did so, I received the following error:
“Failed to generate API key, The request is suspicious. Please try again.”
However, I want to emphasize that I do not need an API key. I only want to use Google AI Studio through the browser.
Could someone please investigate whether there is an account-level access restriction, entitlement issue, Terms of Service issue, security restriction, or another backend issue preventing my Google account from accessing Google AI Studio?
I would especially like to know whether my account has the necessary access/entitlement to use the browser-based version of Google AI Studio.
I have already completed the usual browser and account troubleshooting, so I would appreciate it if this could be investigated on the Google side rather than receiving general troubleshooting instructions.
Thank you.

Same for me for the past 2 days. I can’t even go to check my API keys

Hello all,

  2. Where are you accessing AIS from? Supported regions
