Yes - Cursor is unusable

Hey, this is a known issue. A lot of users have hit it, and there have been a few fixes since then.

The main thing is you’re on version 2.6.22, and the current stable is already 3.1.x. There were a lot of extension host fixes between those versions. First step is to update to the latest version. Download the newest installer from https://cursor.com and install it over your current one.

If the issue is still there after updating:

  • Run Cursor from Terminal with cursor --disable-extensions. If it works, one of the extensions is causing it.
  • Try cursor --profile-temp. This starts a clean profile with no settings or state.
  • Open Developer Tools via Help > Toggle Developer Tools, go to the Console tab, wait for the error, and paste all the red entries here.
