This is a known issue on Windows. Your network is fine — the checks that pass (DNS, SSL, etc.) confirm connectivity; the ones that fail all depend on the extension host.

A few things to try:

1. Make sure you’re on the latest version. Download from [cursor.com/download](https://cursor.com/download). Some improvements to extension host startup have been made in recent releases.

2. Check the cursor-socket folder. Open Command Prompt and run:

3. Try an isolated extensions directory to rule out corrupted extension state:

4. Check Windows Defender or any security software. Even without a VPN, Windows Defender’s real-time protection can sometimes interfere. Try temporarily disabling it, then launching Cursor. If that fixes it, add an exclusion for `C:\Program Files\cursor\` and the `cursor.exe` / `cursor-socket` processes.

5. Clear workspace storage for the affected project. Back up first — this will remove chat history for that workspace:

There’s an existing thread tracking this issue with more details: [Timeout waiting for EverythingProvider Error](https://forum.cursor.com/t/timeout-waiting-for-everythingprovider-error/158146)

If none of the above helps, could you share the logs from your latest session? Open `%APPDATA%\Cursor\logs\`, find the newest folder, and share the `main.log` and any `exthost` files. That’ll help us pinpoint where the startup hangs.
