System freezes at shutdown or reboot

Brand new KDE Plasma install on an older computer. I can’t reboot or shutdown. It always goes to the logo screen and hangs there indefinitely. The little circle even stops moving.

I have no related crash reports, but I’m a new KDE/Linux user, so I may be looking in the wrong place.
