I think QML in general is broken on Qt 5.15 (or they changed some things that need fixing on the KDE side).

systemsettings outputs the following error message before crashing with a segfault:

"Cyclic dependency detected between "file:///usr/lib64/qt5/qml/org/kde/kirigami.2/styles/org.kde.desktop.plasma/Units.qml" and "file:///usr/lib64/qt5/qml/org/kde/kirigami.2/styles/org.kde.desktop.plasma/Units.qml""
