Hello Google AI Studio Team,

My existing project THƯ VIỆN QR THCS — Trường TH&THCS Nguyễn Khoa Đăng is experiencing a persistent Build Assistant failure.

  • Every prompt returns Invalid argument, including a minimal prompt.

  • A new chat in the same project does not resolve the issue.

  • The problem persists in an incognito browser window.

  • The original project source code and Preview remain visible.

  • The GitHub repository has been verified and contains the application source code.

  • The production application is deployed at thuvienqr.vercel.app

Could you please investigate whether the original applet’s DEV sandbox, Build session, or snapshot service needs to be restarted or repaired?

Please preserve the original project and its source code, version history, Firebase configuration, Authentication, Firestore Rules, role-based access control, database records, and production deployment.

I do not authorize destructive recovery, project recreation, or restoration to an older checkpoint without a verified backup and an explanation of the consequences.

I can provide the exact original applet ID and non-sensitive diagnostic screenshots privately.

Thank you for helping me recover the existing project.
