Hey, this is a known issue with extension host initialization on Windows. The team is aware, but there’s no ETA yet.

Try this:

  1. Check the cursor-socket folder. Open PowerShell as admin and run:

    dir "$env:LOCALAPPDATA\Programs\cursor\resources\app\extensions\cursor-socket"

    If you see a dist\ folder but no out\, create a symlink:

    cd "$env:LOCALAPPDATA\Programs\cursor\resources\app\extensions\cursor-socket"
New-Item -ItemType SymbolicLink -Name "out" -Target "dist"

    Restart Cursor. This workaround helped another user with the exact same error earlier today, thread here: Agent Execution Time Out

  2. If that didn’t help, clear the cache. Fully close Cursor, then delete:

    • %APPDATA%\Cursor\CachedData
    • %APPDATA%\Cursor\Cache
    • %APPDATA%\Cursor\GPUCache

    Launch Cursor again.

  3. Last resort, rename %APPDATA%\Cursor to Cursor_backup and start Cursor with a clean config.

Let me know what worked, or what didn’t.
