So, do I just go back to Windows 10? so far this is the only component that doesn't work as intended but it is crucial that it does work, so any advice is welcome. That app handles the camera, but has nothing that addresses the other functions.

Someone said download LogiTune, install and reset, but no joy there either. Problem is now, the webcam part of the webcam works, but the other functions are not recognized, which is a problem for my Zoom meetings as I used the webcam mic to avoid using my G935 headset in a business meeting. The 'No thanks, I will stay on Windows 10 for now' option was ignored and the upgrade proceeded without my consent. THEN Microsoft, in its infinite wisdom decided I needed to upgrade to Windows 11. Webcam, webcam Mic and Webcam speakers all working as intended. The support guy, Siddharth S, is not as wise as his namesake, because he doesn't seem to get the crux of the problem with is almost comical in its absurdity. The graphics I posted capturing the situation may not come through here, but are on the Logitech support message board with the thread. Gonna repost here because I seem to have drawn the short straw when getting a response from anyone with competence from Logitech, though I still have hope.

I posted this on the Logi website for support and got nothing of value.
