Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, thanks for the detailed report. The Request ID and version info really help.

This looks like a known issue with the Glass layout on Nightly. Your build 3.7.9, built 2026-06-04T01:45, was released a bit before the fix that addresses this case. In Glass, the workspace trust prompt was not showing, so an untrusted workspace would quietly block the agent extension from starting. That’s why you see ERROR_EXTENSION_HOST_TIMEOUT after 30 seconds.

What you can do right now:

  1. Update Cursor to the latest Nightly, newer than June 4. The fix is included there.
  2. If you need to unblock before updating, here’s a workaround: run cursor --classic from Terminal, click Trust for the project folder, then switch back to Glass. Once the workspace is marked as trusted, the agent should work.

Let me know if it works after the update.
