Preview fails with "ProvisionAndInitializeApplet" (HTTP 500) after adding features to my app

Hello, I have an application developed in Google AI Studio called “Portal de Compras - Escola de Jiu-Jitsu United”. The application was working correctly until recently. After adding new features, the Preview stopped loading. The Preview now always displays: “Failed to load app” I performed several troubleshooting steps: - Created a Remix of the project. - Restored previous versions. - Removed recent code changes. - Disabled Firebase usage. - Created a brand new test app with only a simple text page. The problem still occurs. Using Chrome DevTools, I found that the Preview fails before the application starts. The failing request is: ProvisionAndInitializeApplet It returns: HTTP 500 Internal Server Error Response: [13,“Internal error encountered.”] Since even a brand new application fails in Preview, I believe this is related to the AI Studio Preview provisioning service or my account rather than my project code. Could you please help me identify: 1. Why is ProvisionAndInitializeApplet returning HTTP 500? 2. Is there any issue with my AI Studio workspace or account? 3. Is my project in a corrupted state? 4. Is there any way to repair or reinitialize the Preview environment without recreating the project? 5. Can you verify if this is a known issue on the AI Studio backend? I can also provide screenshots of the Network request and the full browser console if needed. Thank you.
