Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, thanks for the report. I couldn’t reproduce this on my side, so it might be something specific to your environment.

Can you share a few things so we can narrow it down?

  1. The request ID from the failed attempt (chat context menu in the top right > Copy Request ID)
  2. The developer console logs at the time it freezes (Help > Toggle Developer Tools > Console tab, look for red messages)
  3. What the indexing status shows at that time

Also, do you have any extensions installed, or is this a completely clean Cursor install?
