I can't utilise PipeWire cameras in OBS on my desktop, but can on my laptop

I own a Logitech BRIO. On my Framework 16, although it’s strangely limited to 1080p@30fps in obs-studio (Flatpak and RPM), in both it works via PipeWire (despite t/125900/2). However, on my desktop, it doesn’t work via PipeWire, at all:

Does anyone have any idea of how I might ascertain why?
