Fascinating. If this happens again I’ll try that (hopefully it doesn’t). Turn off, unplug, wait, turn on.
Just to provide another detail for future readers, Fedora/KDE did detect the AC connection and automatically activated my AC performance profiles when I was plugged into the bugged ports. This is part of why I had originally suspected that something had gone wrong with my dGPU under bios 3.07, as my device was still running with my AC mode scripts. Only a closer investigation showed that I was actually on battery.
