Not sure if this is any help but when my PC updated to windows build 17134 ( some time ago) my Logitech webcam stopped working & it cashed the PC when I tried to open the webcam etc.I tried reinstalling drivers/Logitech software etc.but none of that worked. What I did in the end was to make it all work was, I had to go into the Privacy settings & turn on " allow apps to access your camera" this had some how got turned off in the update/upgrade to windows 17134, hope this will work for you.
