Target Milestone: ---
Application: plasma-systemmonitor (5.21.0)
(Compiled from sources)
Qt Version: 5.15.2

-- Information about the crash:
- What I was doing when the application crashed:
Open System Monitor
Looks like this is caused by it expecting the directory
/sys/fs/cgroup/unified/user.slice/user-1000.slice/user@1000.service to be there
which it isn't on my system. (/sys/fs/cgroup/unified/user.slice doesn't exist)
The crash can be reproduced every time.
-- Backtrace:
Application: System Monitor (plasma-systemmonitor), signal: Aborted
