GitHub Sync Stopped Working After Re-authentication – "Failed to load file differences"

Hello,

I am experiencing a persistent GitHub synchronization issue in Google AI Studio Build and would appreciate assistance.

Repository:
wqxvx46mfc-svg/johnny-padel-club

Issue:
The workspace is connected to GitHub and correctly displays:

“Sync to GitHub → wqxvx46mfc-svg/johnny-padel-club on main”

However, the GitHub panel consistently shows:

“Failed to load file differences”

As a result:

  • AI Studio does not display modified files
  • AI Studio cannot generate a commit candidate
  • AI Studio cannot push changes to GitHub

What I have already verified:

  • GitHub repository is accessible and healthy
  • The repository exists and the main branch is available
  • Changes are successfully saved inside the AI Studio workspace
  • New files created inside the workspace are visible locally
  • Browser refresh does not resolve the issue
  • Reconnecting GitHub does not resolve the issue
  • ZIP export works correctly
  • The issue started after AI Studio requested GitHub re-authentication

This project was syncing correctly before the problem appeared.

Could you please investigate whether the workspace snapshot and GitHub diff/index service became desynchronized?

Screenshots available upon request.

Thank you.

Hello, thank you for the screenshot. Since Google AI Studio is not appearing in your GitHub "Installed Apps," please ensure that no remnants of the application remain. By checking the Authorized GitHub Apps or Authorized OAuth Apps sections and ensuring nothing related to Google AI Studio is still listed, you can then attempt to re-authorize the connection directly through the Google AI Studio interface. If you are still facing this issue after re-authorizing, please let us know.

Thank you for the reply.

I checked both GitHub Apps and Authorized OAuth Apps.

Google AI Studio does not appear in Installed GitHub Apps.

I have already removed previous authorizations and attempted to reconnect.

The repository still appears connected inside AI Studio and shows:

“Sync to GitHub → wqxvx46mfc-svg/johnny-padel-club on main”

However, the GitHub panel still displays:

“Failed to load file differences”

and AI Studio cannot detect even newly created files.

For example, I created a new file named:

ai-studio-test.txt

with the content:

test

The file appears in the workspace, but AI Studio still cannot detect it in the GitHub panel.

Could you please clarify exactly which GitHub authorization entry should exist after a successful AI Studio connection?

At the moment it seems AI Studio believes the repository is connected, while GitHub does not show a corresponding AI Studio authorization.

Thank you.
