AI chat panel not responding

[Al_H]

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

I got this issue right after updating Cursor app today. The ai chat has not been responding and the chat panel kept showing either the error message below or simply staying at “generating”.

(Note: I can still manually edit and run the code; I also ran the diagnosis for the network and was all good)

Please help. Thank you!

Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, thanks for the report.

Usually this error happens because Git is missing. Agent mode needs Git installed to work.

Try this:

1. Check Git: open Command Prompt and run git --version
2. If Git isn’t installed: download it from Redirecting… and make sure you select the “Add Git to PATH” option during setup
3. After installing, fully restart Cursor
4. If the issue still happens, enable Legacy Terminal Mode:
   • Ctrl+Shift+J → Agents → Inline Editing & Terminal
   • Turn on “Legacy Terminal Tool”
   • Ctrl+Shift+P → “Terminal: Kill All Terminals”
   • Fully restart Cursor

Similar cases: Stuck with timeouts?

Let me know if installing Git fixed it.
