Hey, this is a known class of bugs with the extension host. The issue is being tracked, but I can’t share an exact ETA for a fix yet. The stack points to macOS, but to be thorough please fill in the template with your Cursor version About Cursor > Copy, your OS version, and what you’ve already tried.

For now, try these steps in order:

  1. Reload the window: Cmd+Shift+P → Developer: Reload Window. If that doesn’t help, fully quit Cursor and open it again.

  2. Start Cursor from Terminal with extensions disabled:

    cursor --disable-extensions

    If it works like this, one of the extensions is blocking the extension host. Enable Extension Monitor: Settings > Application > Experimental > Extension Monitor Enabled, then Cmd+Shift+P > Developer: Open Extension Monitor.

  3. Clear cache:

    • Fully quit Cursor
    • Delete these folders: ~/Library/Application Support/Cursor/Cache, ~/Library/Application Support/Cursor/CachedData, ~/Library/Application Support/Cursor/GPUCache
    • Start Cursor again

  4. Check the cursor-socket contents:

    ls /Applications/Cursor.app/Contents/Resources/app/extensions/cursor-socket

    You should see an out/ or dist/ folder. Send the output here.

  5. If nothing helps, open Help > Toggle Developer Tools, go to the Console tab, wait until the error shows up when you send a request in chat, then send all red entries here as a screenshot or as text.

Let me know which step worked, or what output you got.
