Thanks for the bug report. After plasmashell restarts, it sounds like the powerdevil service may have crashed, and is not restarted along with plasmashell, causing the error in the Power Management UI. We need a little more information to determine what's happening so we can look into fixing it.

1. Please copy the output of the following command - when the bug is present in the Power Management UI - into a reply:

systemctl --user status plasma-powerdevil.service

2. See if there's a coredump for plasma-powerdevil with

sudo coredumpctl --reverse | grep powerdevil

If that has no output, there is no coredump for powerdevil. If there is at least one entry, can you please attach a backtrace of the most recent crash using the coredumpctl command-line program, as detailed in https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl ?

Thanks.
