Hey, this is a known issue the team is looking into. The extension host sometimes can’t register the agent execution provider before the timeout. It shows up mostly on Windows and Linux on 3.1.x and 3.2.x. I can’t share an ETA for a fix yet.

For now, try these workarounds:

  • Legacy Terminal: Cursor Settings > Agents > enable Legacy Terminal.
  • Reload Window: run Ctrl+Shift+P, then Developer: Reload Window.
  • Start without extensions to check for conflicts: from a terminal run cursor --disable-extensions. If the error goes away, one of your extensions is causing it, often Git Blame or similar. See this thread: Initializing extensions... breaks extensions functionality and slows down Cursor IDE
  • Fully restart Cursor. Quit all windows, not just close one.

If none of that helps, please send:

  • Output from Ctrl+Shift+P then Developer: Open Process Explorer, and whether there’s a stuck extensionHost process.
  • Your list of enabled extensions.
