Looks like this is just for go repos

Hey, thanks for the report. I can see the screenshot with the error. The `Wsl/Service/E_UNEXPECTED` error usually means the WSL service itself can’t start properly. That’s on the Windows side, not Cursor.

Try these in order:

1. In PowerShell run `wsl --shutdown`, then reopen Cursor
2. Update WSL: `wsl --update`
3. Inside WSL delete Cursor server files `rm -rf ~/.cursor-server`, then reconnect
4. If that doesn’t help, reinstall the WSL extension in Cursor. First close the remote connection with `Ctrl+Shift+P` then Remote: Close Remote Connection. Open a local project, find the WSL extension, uninstall it, restart Cursor, then reinstall it when prompted.

More context here: [Cursor WSL error: Failed to patch code.sh launcher](https://forum.cursor.com/t/cursor-wsl-error-failed-to-patch-code-sh-launcher/155773)

Also, you said it’s “just for go repos”. Can you clarify? Do other projects work fine through WSL? If yes, it might be something specific to the Go workspace, not a general WSL issue.

A couple questions to help diagnose:

- Which WSL distro are you using?
- What does `wsl --version` show in PowerShell?

Let me know how it goes.
