Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, this is a known bug with extension host initialization on Windows, reinstalling the OS won’t help since the installer creates a dist/ folder without out/ in the cursor-socket extension.

Open PowerShell as admin and check the folder contents:

dir "$env:LOCALAPPDATA\Programs\cursor\resources\app\extensions\cursor-socket"

If you see dist\ but there’s no out\, create a symlink:

cd "$env:LOCALAPPDATA\Programs\cursor\resources\app\extensions\cursor-socket"
New-Item -ItemType SymbolicLink -Name "out" -Target "dist"

Restart Cursor.

If the symlink didn’t help, try enabling HTTP/1.1 in Cursor Settings > Network. The team is aware of the bug, there’s no ETA for a fix yet. Let me know if this worked.
