AI Studio Build Agent fails only in my original project

I have a reproducible project-specific Build Agent failure.

Original project: Aeroplane Ludo Game Engine

In the original project, every Build Agent request now returns:

“Encountered retryable error from model provider: Agent execution terminated due to error.”

AI Studio also displays:
“You’ve reached your limit for the day. You can wait for it to reset or upgrade to continue.”

This has persisted for more than two days.

I tested the same Google account in a different browser and the problem remains.

Control tests:

  1. New AI Studio chat → TEST OK → SUCCESS
  2. Remix of the same Aeroplane Ludo project → PROJECT COPY TEST OK → SUCCESS
  3. Original Aeroplane Ludo project → even the trivial prompt PROJECT TEST OK → FAIL

Therefore, the problem appears isolated to the original project’s Build/Agent environment or project session, rather than my Google account, browser, prompt, or application code.

The original project is backed up in GitHub.

Please investigate the Build/Agent environment for this specific project and restore its ability to execute Build Agent requests. Please do not modify, reset, or delete my project files.

Screenshots of the error and successful Remix test are attached.

Hi Payal,

Thank you for getting back to me. Please find the requested information below:

  • Original applet ID: a95d81ff-f6cb-41df-a5b0-d1cd4a4bd7..
  • Remixed applet ID: bd4f552e-1157-4e66-bffc-071304366e..
  • Email address: `[t…@gmail.com
  • Subscription: Free tier

The problem occurs only in the original Aeroplane Ludo Game Engine project. The remixed copy works normally.

The original project consistently produces the “Agent execution terminated due to error” / “You’ve reached your limit for the day” behavior even with very simple prompts, while the remixed project can execute the same type of test prompt successfully.

I would appreciate it if you could investigate whether there is a project-specific issue with the original applet/environment, rather than a general account or browser issue.

Thank you for your help.

Regards,
Dr. Rajendra Kumar

Thanks for providing the details. We have passed this to our internal teams as feedback.

Hi Payal,

I provided the requested Applet IDs and account information. Unfortunately, the issue is still completely unresolved after approximately 10 days.

The original Aeroplane Ludo project continues to fail Build Agent execution, including with extremely simple test prompts. The Remix copy works normally under the same account/environment.

This is now preventing me from continuing development of the original project. Could the AI Studio team please investigate the original Applet directly and let me know whether its Build Agent/generation state is stuck or corrupted?

I would greatly appreciate an escalation or direct investigation of the original Applet.

Thank you.
