Hey there! Thanks for flagging this - it’s an issue we’re tracking with the Windows updater, not your setup. Reinstall from cursor.com/download (settings under %APPDATA%\Cursor stay), and don’t shortcut the _ folder under the install dir.
To cut how often it happens: in the Editor (Ctrl+,), set update.mode to start, fully quit Cursor before Windows shutdown, and exclude %LOCALAPPDATA%\Programs\cursor in Bitdefender/Defender. Same class: Windows: Desktop shortcut breaks after auto update. I’ll post here when there’s an update.
