Hey, thanks for the report. This is a known issue. The Browser tab crashes or becomes unresponsive after you move it into a separate window.
Main tracking thread: Bug: Browser tab unresponsive after moving to new window (v2.4.22)
Workaround:
- Keep the Browser tab in the main Cursor window
- Or open your page directly in a regular browser
