I'm on 22H2 2261.2361 with Copilot Preview installed. It was working fine for several days until today where I decided to launch it. Launching it from the taskbar doesn't launch it successfully. No errors shown. Nothing in the Event Viewer at all. I'm guessing something server side is botched and it's failing really early in initialization on launch.
I am an IT Technician and figured out the copilot not opening issue after spending several hours on it, you have to delete your Edge profile and then it works fine. Hope this helps.
