Hey @ssr!

It looks like you’re on a pre-release version. We fixed this issue on main this morning. It still needs to go out in a release, which should happen today, but in the meantime you can revert to a stable version.

@manuchermunakov-bit Can you share the information in your Cursor > About Cursor?

Look, the situation is this: I’ve just identified the root cause of the problem, but I don’t know how to fix it yet. This error really did occur for me, and the cursor was on the desktop - reinstalling helped (the latest stable version). However, when I launch the app from the desktop, the problem comes back. It only works when launched from the root directory.

Do I need to manually look for leftover junk from the buggy version?

Hey @munakovManucher

This version doesn’t look like the latest stable version. It looks like a nightly build.

  1. Make sure that your Update Access is set to Default

  2. This should auto-update you back to a stable version, but if not you can download it from https://cursor.com/download
