Possibly related: on openSUSE 15.1, those same widgets are completely blank.  Other widgets work (eg: clock).

This is with Plasma 5.18.90, Qt 5.14.1, using the openSUSE RPMs.

The error message about QML is no longer appearing on my system.
But none widget is functional.
Comment 3 Marco Martin 2020-05-27 08:38:38 UTC
did the error message went away after updating neon? (the error looks like a packaging problem)
on the second error: does restarting help?

another thing you can try (that would give some info) is to try to stop plasmashell, launch from terminal ksystemstats, then start plasma again
Comment 4 S. Bryant 2020-05-27 08:39:45 UTC
I'm seeing output like this from 'plasmashell':

file:///usr/share/plasma/plasmoids/org.kde.plasma.systemloadviewer/contents/ui/SystemLoadViewer.qml:253: TypeError: Cannot read property 'value' of undefined

The widgets are funcional after today's updates. :)
Comment 6 S. Bryant 2020-06-13 21:29:26 UTC
While the bug is fixed, the widgets have been rewritten and may not appear fixed.  It may be necessary to tweak the settings to be able to see some of the graphics - including resizing the widget and/or removing the widget background (depending on theme).
