AI Studio GitHub Synchronization Broken After GitHub Re-Authentication

Hello,

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

Repository:
wqxvx46mfc-svg/johnny-padel-club

Branch:
main

What happened:

The project was working normally.

Google AI Studio was connected to GitHub and successfully detecting file changes, generating commits, and pushing updates to the repository.

While working on the project, AI Studio requested GitHub authentication again.

As I have done successfully in the past, I:

  1. Opened GitHub
  2. Removed the existing integration
  3. Re-authorized GitHub access
  4. Returned to AI Studio

After re-authentication, the repository still appears connected.

AI Studio displays:

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

However, synchronization stopped working completely.

Current symptoms:

The GitHub panel continuously shows:

“Failed to load file differences”

Because of this:

  • AI Studio does not display modified files
  • AI Studio cannot calculate diffs
  • AI Studio cannot generate commits
  • AI Studio cannot push changes to GitHub

What I verified:

  • The repository exists and is accessible in GitHub
  • The repository remains on the main branch
  • AI Studio still shows the repository as connected
  • Local changes exist inside the workspace
  • I created a test file named ai-studio-test.txt containing the word “test”
  • The file appears in the workspace but AI Studio still cannot detect it in the GitHub diff panel
  • Hard refresh does not help
  • Reopening AI Studio does not help
  • Reopening GitHub does not help

Important observation:

The issue started immediately after GitHub re-authentication.

Before re-authentication:

  • AI Studio detected changes normally
  • GitHub synchronization worked correctly

After re-authentication:

  • Repository link remains visible
  • Diff engine stopped working
  • File differences cannot be calculated

This suggests the problem is related to AI Studio’s GitHub synchronization state rather than the repository itself.

Additional information:

  • A full ZIP backup of the project was created before troubleshooting
  • No force push was performed
  • No branch changes were made
  • No repository rename occurred
  • The repository remains healthy and accessible

I have also opened Issue Tracker bug:

524406290

Requested help:

  1. Why AI Studio cannot calculate file differences after GitHub re-authentication
  2. Whether the workspace Git synchronization state became corrupted
  3. How to rebuild or reset the GitHub synchronization index without losing current workspace changes
  4. Whether this is a known issue affecting GitHub integrations in AI Studio Build

Thank you.
