MSI B850 Tomahawk was working but stopped

Any guidance? I have MSI’s mystic light software installed but not running on startup. I also have iCue but again not starting unless manually (ie if I’m playing Terraria I like the keyboard effects for that game but otherwise I keep it off).

I’m unsure what I did if anything, but recently my motherboard-connected devices (two light strips and an alphacore GPU block) all stopped working. My RAM continues to work as usual.

This is a win11 machine. Thanks for any insight.
