Hey, I can see this is a continuation of your previous thread [Urgent - Cursor doesn't work with errors "Agent Execution Timed Out"](https://forum.cursor.com/t/urgent-cursor-doesnt-work-with-errors-agent-execution-timed-out/155029), thanks for posting the directory listing of the `cursor-socket` folder there. That’s the key clue. In your `cursor-socket` folder, you have `dist/`, but there’s no `out/` folder. The extension expects its entry point at `./out/main`, so when `out/` is missing, the extension host crashes right away. Try this workaround. Open Command Prompt as administrator and run: ```bat cd "%LOCALAPPDATA%\Programs\cursor\resources\app\extensions\cursor-socket" xcopy dist out\ /E /I ``` This will copy the contents of `dist/` into a new `out/` folder. Then restart Cursor. One more thing I didn’t ask earlier. Do you have any VPN software installed, even if it’s not running right now. Another user with the exact same issue fixed it by uninstalling their VPN app [Extension host terminated unexpectedly no matter what i try - #9 by Brian\_Walch](https://forum.cursor.com/t/extension-host-terminated-unexpectedly-no-matter-what-i-try/154429/9) This is a known packaging issue on our side. I’ve flagged it to the team, your report and the file list help us prioritize it. Let me know if the `xcopy` workaround helped. ---

Thank you very much @Dean. Cursor is restored and I’m working with it now. In Windows 11, `cursor-socket` folder is located in `C:\Program Files\cursor\resources\app\extensions\cursor-socket`. BTW, xcopy command fixed the issue. Thanks again! ---
