KDE "Power Management configuration module could not be loaded"

I opened my computer and noticed a notification pop-up on the taskbar, saying something about KDE power management not working. Then I went to the power management settings and was presented with this

I'm on a desktop so not sure how necessary this is to have. But it was certainly working before.

Re: KDE "Power Management configuration module could not be loaded"

I noticed that the powerdevil applet wasn't loading after today's pacman update, and the org_kde_powerdevil process kept crashing and restarting.
ddcutil 2.1.0 seems to be the culprit, downgrading this package to 2.0.0 fixes the issue for now (at least on my end).

Thanks!  Downgrading ddcutil worked for me too.  Was afraid I'd have to downgrade all the KDE packages.

Let's Go. Downgrading solved the issue!

It's fixed in ddcutil-2.1.0-2.
