I am locked in a broken authentication sync loop between Google AI Studio and GitHub. After manually removing/revoking the Google AI Studio application permissions directly from my personal GitHub settings (`vatsal..`), the Google AI Studio backend failed to register the revocation.

The web interface is now permanently stuck on a backend permissions error screen. Because it is trying to evaluate an old, deleted OAuth token, it completely hides the blue “Sign in to GitHub” button. This prevents me from triggering a clean re-authorization handshake.

**Error Messages Encountered:**

1. _“Sync to GitHub: [username]/[repo] on main. Failed to load file differences.”_

2. _“Something went wrong. Failed to create GitHub repository, Insufficient permissions to create the GitHub repository. Please check your permissions for the AI Studio App on GitHub.”_
