I have the same issue. Currently not able to even load the page options for wallpaper in sys prefs - though I have.a rotating wallpaper each minute on a shared icloud drive folder that might be causing a hiccup.. not sure.
only an issue on mac mini m1. mbp 13in m1 still able to access wallpaper page in sys prefs.
cheers,
