Hello Cursor Support Team.
I’m here as I need your help.
I used Cursor till this morning, but I updated my Windows OS.
After that, I have the error messages whenever I send prompt.
“Agent Execution Timed Out
The agent execution provider did not respond in time. This may indicate the extension host is not running or is unresponsive.”
With this one, I face the error - “Extension host terminated unexpectedly 3 times within the last 5 minutes.”
I’m not sure the reason and I want to fix this issue asap.
I’m sharing full logs in Cursor Developer Mode.

Steps to Reproduce
When I submit my prompt, it shows the above errors and it doesn’t work.
Hey, thanks for the report. This is a known issue. The extension host crashes on Windows, and that can trigger the Agent Execution Timed Out error. Since it started right after a Windows update, that matches what we’ve been seeing.
Let’s try a few things in order:
Disable Codebase Indexing:
Cursor Settings (not VS Code settings) > Indexing & Docs > turn off Codebase Indexing. If you also see Index Repositories for Instant Grep (BETA), turn that off too. Restart Cursor.
Try a temporary profile:
cursor --profile-temp
This starts Cursor with a completely clean state. If it works, the issue is in your profile or state data.
Check cursor-socket:
Open Command Prompt and run:
dir "%LOCALAPPDATA%\Programs\cursor\resources\app\extensions\cursor-socket\"
We’ve seen cases where the out/ folder is missing inside cursor-socket, and that makes the extension host crash right away.
Check for VPN software:
Another user with the exact same issue found that uninstalling VPN software fixed it, even if it wasn’t running. If you have any VPNs installed, try removing them temporarily. Extension host terminated unexpectedly no matter what i try
Also, since this started after a Windows update, a fully clean reinstall might help:
Uninstall Cursor
Delete %APPDATA%\Cursor and %LOCALAPPDATA%\Programs\cursor
When I submit my prompt, it shows me “Waiting for Extension Hosting” instead of “Planning next moves”.
And when I tried 3rd method, it shows me below logs. I’d love you to check this one and let me know if this is correct or this is the main reason.
