I have random systemsettings5 crashes when trying to access some menus, for example if I go to Workspace behavior -> Desktop Effects it crashes with following journal log:

You have to import QtQml 2.15 after any QtQuick imports and set

Not sure how to find the reason. If anyone has some places to look at or some things to try to reset some things please share.
//EDIT: seem fixed by deleting ~/.config/plasmashellrc and ~/.config/plasma-org.kde.plasma.desktop-appletsrc then rebooting and reconfiguring a few things.
//EDIT: also KDE Application launcher doesn't open when Meta key is pressed
