Cursor IDE

Describe the Bug

Request ID: e7d0ddb3-988d-439a-bc81-1898f0670498 (details below)
I’m on latest version (details below).

As a last ditch effort, I re-installed & the issue still exists.

Tried starting with “cursor --disable-extensions” but the issue persists.

Any ideas ?

Steps to Reproduce

When I start cursor IDE - it shows me an error - “Extension host terminated unexpectedly”.
And all composer requests fail after “Planning next moves”.

Expected Behavior

It should plan & execute code changes

Additional Information

Re-installing + Restarting didn’t help.

Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, this is a known issue. The extension host cursor-socket can’t start, and all AI requests time out. The team is aware, and the bug is logged.

A few things to try:

  1. Check the cursor-socket folder contents. Open PowerShell and run:
dir "$env:LOCALAPPDATA\Programs\cursor\resources\app\extensions\cursor-socket"

You should see an out\ folder or dist\. If there is no out\ but there is dist\, create a symlink:

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

You need to run PowerShell as admin.

  1. Try opening a new Agent window instead of the current one. One user with the same error got unstuck that way.

  2. Turn off Codebase Indexing: Cursor Settings > Indexing & Docs > turn off Codebase Indexing. Then reload the window using Ctrl+Shift+P and run Developer: Reload Window.

  3. If none of the above helps, open Developer Tools via Help > Toggle Developer Tools, go to the Console tab, wait for the error to show up, and paste all the red entries here.

Let me know how it goes.

I think I had copied it directly instead of creating the symlink.. which didn’t work.

I also, disabled the index repositories for Instant Grep Beta.

One of those worked !
