Strange just had the same issue happen. I just figured it was related to me using windows 11 on unsupported hardware, but apparently it isn't. Did exactly what you did and it now works on both screens again.
What I do notice is a severe lag in the application window when sliding it from one monitor to another.
It bothers me as well.
Edit : And now its working again I had one update 7zip, installed it with patchmypc, and just after the message appeared it was done, explorer crashes on me and resets :-) Fortunately patchmypc remains visible. Windows 11 is such a mess lol.
