Demonstration

If you go into the settings, you can see that the system wallpaper is not loading

STEPS TO REPRODUCE
1. Go to Settings => "Screen Locking"
2. Go to Appearance
3. Switch the wallpaper mode to "Image"
4. You will see that you cannot select a wallpaper. They just didn't load.

OBSERVED RESULT
It's empty, there's no wallpaper.

EXPECTED RESULT
I had to see a list of all the wallpapers

SOFTWARE/OS VERSIONS

KDE Frameworks Version: 5.246.0
