I have also just encountered the same issue! so i'm not sure if my windows updates were a little behind, but i can now disable the audio from the webcam (as per other threads) to ensure the webcam works and doesn't crash all audio
but i cannot run AUDIO + WEBCAM through the webcam... I have not tried disabling core isolation, as I don't know how important it is...
But this is as per other's posts, ridiculous that a quite expensive and relatively new webcam crashes your computer , or its full functions aren't enabled due to some random update!!!
