Hey, this is a known issue. The integrated browser crashes Cursor when you move it into a separate window. A few users are seeing the same thing:

The team is aware. For now, the workaround is:

  1. Keep the Browser tab in the main Cursor window, don’t use Move into New Window
  2. Or open localhost in a regular browser on your second monitor

Let me know if the workaround doesn’t work for you.
