Unresponsive AI Pane on a specific workplace

Support Bug Reports

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

Workplace stopped taking prompts after a few days of developing a unity project.
Sending prompts in the specific folder does not function, pressing enter or the upwards arrow for send on the AI Pane does nothing, pressing it again turns it into a square as if the prompt is being processed but nothing is happening.
Other folders work, but not the main one.

Steps to Reproduce

I can open the affected workplace at any time

Expected Behavior

I expected it to at least tell me why it wouldn’t process my prompt but nothing is happening at all

Additional Information

The unity project had become a bit complex but not data science, I don’t think its complexity related but it did happen after a while of developing so I don’t know

Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey, thanks for the report. It looks like a workspace‑specific issue where the AI pane gets stuck processing.

Try this:

  • Fully restart Cursor, sometimes the AI service gets stuck on a single workspace.
  • Check for large files or generated Unity assets that might slow context processing.
  • Temporarily move large Unity folders (Library, Temp, Logs) outside the workspace and see if the pane responds.
  • Review your workspace settings, something there might be causing the hang.
  • The issue may also be related to one or more extensions. Try launching in safe mode: cursor --disable-extensions. Also check the Process Explorer panel, it may show the cause.

If that doesn’t help, see the troubleshooting docs:
