Hey, thanks for the report. To narrow down the cause, I need a bit more info:

  1. Exact Cursor version (Help > About Cursor > Copy)
  2. macOS version
  3. Please try launching from Terminal with cursor --disable-extensions and see if it crashes again
  4. If it still crashes, open Developer Tools (Help > Toggle Developer Tools) before it happens and share any red errors from the Console tab

Also, try the workaround from the linked thread: delete or rename the state database file:
~/Library/Application Support/Cursor/User/globalStorage/state.vscdb
(you’ll need to sign in again after that)

If you have a large workspace (100,000+ files), that can also affect it. Let me know the approximate project size.
