This seems a generic error page from ComfyUI. can you also send the screenshot of what you have seen when you clicked on `Open Logs` : ) ---

I think you likely have two versions of ComfyUI Manager installed. Can you delete the one in your chosen install location? Desktop already comes with Manager so you don’t need to install another one. Also can you try 0.4.18 (latest)?
