Cursor application window opens successfully but the editor interface fails to render, leaving a blank/empty window. The application appears to start normally but the main UI components do not display.
Steps to Reproduce
Launch Cursor from terminal or click desktop icon.
Expected Behavior
Cursor should open with the full editor interface visible.
Critical Errors Found
I started Cursor using the command cursor --verbose --enable-logging=stderr and obtained some error messages.

I recall that when I attempted to open the AI chat window in a new tab, the Cursor application crashed, even though it was working perfectly fine before that.
