SUMMARY

I've been having lots of issues with my computer going to sleep lately.
When I let the system go to sleep on it's own from inactivity, it will turn the
monitors off for a few seconds, then immediately wake up. It'll then be in a
state in which if I play a video, it will freeze for several seconds or
minutes. To get out of this state, I have to type "systemctl --user restart
plasma-powerdevil.service", and it'll be able to play videos without freezing,
but it still won't be able to sleep.
Note: This only seems to happen with "Turn off screen", not with actually
sleeping.
These are the logs from the last time I tried to let the system turn off the
screen on it's own:

ADDITIONAL INFORMATION
This seems similar to https://bugs.kde.org/show_bug.cgi?id=480026. The issue
says "resolve/fixed", but I still have this problem, so I don't know if it's
the same one.
If I run the same command as in the bug, `dbus-send --session --print-reply
--dest=org.kde.kglobalaccel  /component/org_kde_powerdevil
org.kde.kglobalaccel.Component.invokeShortcut string:'Turn Off Screen'`, I get
a similar looking issue, and this shows up in my journalctl:
