Error loading QML file in manjaro system settings

When opening manjaro system settings certain tabs (like Global Themes/Plasma Themes/Colors/Icon) display a “Error loading QML file” error.

I have a screenshot but the forum is not letting me upload images or put links. The screenshot is in imgur dot com /a/5DZDtdD

The error also displays lines like:
file:///usr/share/kpackage/kcms/kcms5_icons/contents/ui/main.qml:259 Type NewStuff.Button unavailable

Please provide from terminal:
pacman -Qs plasma-desktop

That error was from way back and was fixed since 5.18.0-3

It says
local/plasma-desktop 5.20.2-1 (plasma) KDE Plasma Desktop
