Hey, this is a known issue with the extension host on Windows. cursor-socket can’t initialize, and all extensions get stuck.

A few things to check:

  1. Open PowerShell as admin and check the contents of the cursor-socket folder:
dir "$env:LOCALAPPDATA\Programs\cursor\resources\app\extensions\cursor-socket"

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

cd "$env:LOCALAPPDATA\Programs\cursor\resources\app\extensions\cursor-socket"
New-Item -ItemType SymbolicLink -Name "out" -Target "dist"
  1. Try launching Cursor with a temp profile:
cursor --profile-temp

  1. Turn off Codebase Indexing: Cursor Settings (not VS Code settings) > Indexing & Docs > turn off Codebase Indexing. Then run Ctrl+Shift+P and select Developer: Reload Window.

  2. If nothing helps, go to Help > Toggle Developer Tools > Console, wait for errors, and paste all red entries here.

Also, which Cursor version are you on? Check Help > About.

The team is aware of this issue. There isn’t an exact ETA yet, but your report helps with prioritization.

Let me know how it goes.

Update for anyone who finds this thread later: in most cases, the root cause of this freeze on Windows is AV or EDR software antivirus or endpoint security that blocks the extension host or cursor-socket. If the workarounds above don’t help, try temporarily disabling your AV or EDR, or ask IT to add Cursor to the exclusions list. The symlink fix and --profile-temp can reduce the symptoms, but if the AV is intercepting processes, the issue will come back.
