Local models occasionally crash and stop at old loading UI

[FloareDor]

Problem

Intermittent crashes have been observed when using local models—the application sometimes gets stuck at the old loading UI instead of progressing or recovering. This prevents users from getting their answers and requires a manual refresh or restart to continue.

Steps to Reproduce

1. Paste a GitHub URL and ask a question using a local model configuration.
2. Occasionally, during loading, the UI displays the old loading screen and never progresses.
3. Inspect logs or developer tools; sometimes no clear error is shown.

Expected Behavior

The UI should reliably either complete the response or at least recover/timeout gracefully if a crash occurs.

Actual Behavior

• Loading UI remains visible indefinitely.
• No error message is displayed.
• User is forced to refresh the page or restart the app.

Suggestions

• Add error handling or recovery logic for local model loads.
• Ensure the UI fallback updates to the latest version or displays a clear error.
