Monterey purple wallpaper replaces my desktop background every time I reboot
Hello,
I have 5 virtual desktops, two with Apple live background (Monterey and Catalina), one with Mavericks waves and two with my own photos.
Every time my laptop reboots (which is quite too often as Apple releases many bugfixes lately), two live wallpapers are reset to Monterey default purple watercolor walley. Only static wallpapers remain.
Later, as I swipe between desktops looking for "whate else was damaged since yesterday" I notice, that purple walley wallpapers suddenly change to single color, light blue WinXP style background.
Whan I open Preferences/set the live wallpaper, I always have to download it again, because there is a cloud icon near it. When I do it, the same live wallpaper is set to all five virtual desktops! Why?
Should I locate the desktop files and make them read only, so they will survive reboot cleanup?
Monterey 12.3.1 @ MBPro 2015
I have a lot of sarcastic comments now, but I leave it for Twitter. Feedback sent to Apple.
