Hi,
The latest update to the Deepin control center has broken the power management and display options, clicking them just crashes the control center.
A workaround is to revert to an earlier version of Deepin control center - the reversion below worked for me. Check if you have the version below or an earlier version in your pacman cache (look in the directory in the code).
sudo pacman -U /var/cache/pacman/pkg/deepin-control-center-5.3.0.22-1-x86_64.pkg.tar.zst
