Hello Google AI Studio team,

The Build Assistant repeatedly returns “Invalid argument” whenever I submit a prompt. This happens in my existing project and in a separate new project. Starting a new chat did not fix the issue.

The existing app preview still works, but I cannot continue editing or repairing my property management system.

I have downloaded a ZIP backup and need to preserve my existing source code and data. Please investigate this issue and provide a safe fix without requiring me to rebuild the project.

Thank you.

Thank you for restoring my account.

The Google AI Studio Build Assistant issue is still unresolved. I continue to receive “Invalid argument” when submitting prompts in both my existing project and a separate new project.

Could you please investigate the issue and advise me on a safe solution that preserves my existing project and data?

Thank you.
