Hey, I saw your diagnostic screenshots, and it’s the exact same pattern: the basic network checks (Downloads, CDN) pass, but all 4 providers fail with “Timeout waiting for EverythingProvider”. That means your network is fine, and the problem is the extension host not being able to start.
This is a known issue on Windows. Let’s go through the steps:
- Do you have any VPN software installed? Clash Verge, v2rayN, sing-box, or anything else.
Even if the VPN is turned off, it can still break the extension host. In most cases, that’s the root cause. If you have one, fully uninstall it (including the app’s local data), reboot your PC, and launch Cursor again.
- Check the cursor-socket folder
Open Command Prompt and run:
dir "%LOCALAPPDATA%\Programs\cursor\resources\app\extensions\cursor-socket\"
If you see dist\ but there’s no out\, that’s the issue. Fix it like this:
cd "%LOCALAPPDATA%\Programs\cursor\resources\app\extensions\cursor-socket"
xcopy dist out\ /E /I
Restart Cursor.
- Start Cursor without extensions:
cursor --disable-extensions
- If nothing helped, temporarily disable your antivirus or firewall and try again.
Send me the result of each step, and especially your answer to the VPN question. We’ve already fixed a similar case here: Timeout waiting for EverythingProvider
