The only thing I can think of is that we do enable pipewire/libcamera capture in chromium (because this is what all our CSI cameras use). I can't see a reason this would break v4l2 loopback if normal v4l2 (USB) cameras still work, but it could be worth a try disabling this. If you navigate to chrome://flags then search for "pipewire" there's an option called "PipeWire Camera support" which you can disable.
