I remember having a similar problem with my Windows 8 / 8.1 machine. It seemed that on occasion Windows updates caused my printer to stop working. I ended up disabling the Windows updates and all was OK with the printer - not a good solution, as it eventually creates other issues!
I hope this isn't going to be the situation with Windows 11.
I tried downloading the print drivers again to my new machine, but that didn't work. The solution was to completely remove the printer & all its files / drivers & then reload everything from the Canon website - & now the printer is working again!
