I need help fixing this please The agent execution provider did not respond in time. This may indicate the extension host is not running or is unresponsive

Hey, this is a known issue. The error agent execution provider did not respond in time means the extension host didn’t start fast enough ERROR_EXTENSION_HOST_TIMEOUT. This is on our side, and it happens most often on Windows.

What you can try right now:

  1. Fully close and restart Cursor. Not just reload, close all windows.
  2. Update to the latest version. Check Help > Check for Updates.
  3. Reload the window via Cmd+Shift+P or Ctrl+Shift+P then run Developer: Reload Window.
  4. If it still doesn’t help, run cursor --disable-extensions in your terminal to check if a heavy extension is slowing startup.

To help us narrow it down, please share:

  • Your Cursor version Help > About and your OS
  • The Request ID from the chat where you saw the error right top chat menu > Copy Request ID if Privacy Mode is off

We’re tracking this issue, and I’ll post an update in the thread when we have one.
