One UI 4.0 Wallpapers bug

Anyone facing this issue? When trying to set a live wallpaper the live wallpaper app crashes and the wallpaper resets to the default.
Crash reports on Playstore are increasing dramatically every day.
From what i see it has to do with the new icons theming function.

Here is the error log:

The same here! I have a live wallpaper app on the Play Store. Several days ago I started to receive angry letters from owners of Galaxy s21 ultra! More and more developers get that crash log. The topic was also created on stackoverflow.

I hope Samsung developers will fix that bug. IMHO it’s just an unforgivable bug because ordinary users think that live wallpaper developers are to blame!

I am also facing the same problem. The crashes are increasing everyday. As always ordinary users are blaming us. Never expected such a disastrous bug from Samsung.
Hope samsung will solve this bug asap.
