no restart or shutdown action performed

SUMMARY
Since the update to KDE 6.0 (from 5.27) the buttons to shut down or restart the system do no longer work. When I press the power button (it's left at the default behaviour of starting the fullscreen shutdown menu) the shutdown menu does not appear.


STEPS TO REPRODUCE
1. Try to restart or shut down the system

OBSERVED RESULT
KDE neon does just nothing. The buttons can be clicked, but neither a restart not a shutdown are triggered.
When the power button (with default settings) are pressed, the shutdown menu is not displayed.

EXPECTED RESULT
The OS performs the restart or shutdown action as ordered to do so.
When the power button is pressed, the shutdown menu is displayed.
