Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, thanks for the report and the video, it really helps. This is a known issue on the Glass layout side. If the first submit errors, the agent gets archived and the text goes back into the input box with no visible error banner. It’s logged internally, a fix is being worked on, but there’s no exact ETA yet.

A few things that might unblock you right now:

  1. Fully restart Cursor, use Quit, not just closing the window. This has helped in a few cases when it’s a client state issue.
  2. Check Cursor Settings > Network > Run Diagnostics. If you’re on a VPN or corporate proxy, try turning it off temporarily. Sometimes the upstream error that triggers this recovery path comes from there.
  3. If restarting doesn’t help, try switching to the editor window for now. This issue is specific to Glass.

If it keeps happening, it’d be super helpful if you could:

  • Open DevTools via Help > Toggle Developer Tools before pressing Enter, reproduce it, and send anything that shows up in the Console in red.
  • Share the Request ID from the last failed attempt via chat context menu in the top right > Copy Request ID, if it gets generated in time.

Let me know how it goes.

Hi Dean

Thanks for the prompt reply.

I tried 1 - 2 and it didn’t work, but I’m now using editor Window and its good.

I’ll keep an eye out for when the fix comes through.

Thanks!
