[CONFIRMED] Persistent Permission Denied - Drive Files Exist but UI Locked

Google AI Studio
,
1

I am confirming that I am also affected by the “Persistent Permission Denied” bug as of today (December 2025).

Symptoms:

  • My existing projects have disappeared from the sidebar (“No prompts yet”).

  • When opening a file directly from Google Drive, I get the “Prompt cannot be accessed” error.

  • Critical: If I create a new app and save it, it immediately becomes inaccessible upon reloading.

Troubleshooting Already Attempted (All Failed):

  1. Account Verification: Verified I am logged into the correct Google Account (matches Drive owner).

  2. Drive Check: The files physically exist in the “Google AI Studio” folder in Drive. They are NOT in the Trash.

  3. Browser: Tried Hard Refresh (Ctrl+F5) and Incognito Mode.

  4. Permissions: Revoked and Re-granted “Google AI Studio” access in my Google Account permissions.

Impact: I have the source code backed up, but I cannot use the AI Studio UI to edit or redeploy my active applications. This is a complete blocker.

Request: Please check the server-side auth token sync for my account. I have submitted an in-app “Send Feedback” report with my logs as well.

Hey,

Hope you’re keeping well.

This looks like a backend authorization issue rather than a local browser or Drive sync problem. Since the files remain in Drive but AI Studio cannot read them, the most likely cause is a broken token or scope mapping between your account and AI Studio’s backend. You’ve already tried re-authorizing from the Google Account permissions page, but I recommend also signing out of all Google sessions, clearing cookies for ai.google.dev, and logging back in to force a fresh OAuth handshake. If the issue persists, open a support case via Google Cloud Console > Support with your project ID and affected file IDs so the team can check token state server-side. Keep your “Send Feedback” report reference handy, as engineering will need it to correlate logs.

Thanks and regards,
Taz

Hi @Lance_Mald

Thank you for bringing this to our attention.
Apologies for the delayed response. Could you please confirm if you are still facing the same issue?

I lost all the work I did from Thursday December 4- thru Friday Dec 5th. I am still unable to open those files in Google Drive or AI Studio. They return a ‘page not found’ message. It was the latest version of my platform and I had just deployed it on cloud run. Luckily I had dowloaded all my code to my laptop and by opening an earlier version was able to rebuild it. I opened this earlier version and kept it open in AI Studio for several days for fear if I closed it I would not be able to reopen it. I now hold my breath every time I open a file in AI Studio, and don’t relax until it is fully loaded. To this day I do not understand how this happened.
