Google AI Studio → GitHub Push Failure for Existing Production Project – “Failed to push commit to GitHub”

Hello Google AI Studio Team,
I need assistance with a persistent GitHub synchronization failure in Google AI Studio Build Mode.
Project: MarketPilot AI Production
GitHub repository: fastone-sa/MarketPilot-Ai
Branch: main
The project contains substantial production work and hundreds of changed files. AI Studio recognizes the GitHub integration, but when attempting to synchronize/export the current workspace, it fails with:
“Failed to push commit to GitHub. Please try again.”
The AI Studio runtime cannot independently complete the push through CLI because the environment is non-interactive and does not have usable GitHub credentials.
I need to preserve the existing repository, commit history, and current AI Studio workspace. I do not want to delete the repository or create a replacement repository.
Could the AI Studio team please investigate the server-side GitHub binding/authentication state and advise how to restore push capability to the existing repository?
Please let me know what diagnostic information, screenshots, App ID, repository identifiers, or logs you need. I can provide them.
Thank you.
