HP Envy x360 camera not found in device manager

[ListOfPrblms]

Hi. 

I have annoying problem, after one update of system (When I bought laptop, before update, all works correctly), my webcam disappeared from Device Manager. 

My camera and microphone don't work. When I click camera app i see this: 

Frontrunning your answer, a disable switch button isn't a problem. 

I read a lot of similar topics, but I didn't find solution for my problem. I also couldn't found any WebCam driver for my laptop. How is it possible than HP don't support it and provide drivers for webcam?

Device is HP Envy x360 15-dr0003-nw.

Problem appeared when laptop was on warrancy (over 1 year ago), but I didn't need camera and microphone before. Now when I need it, I can't use it. 

I tried to reset BIOS, also I restore my computer, still not working. After all tryings, now my kill switch button also not working. Before when I changed position of button I saw on screen open/off camera (also when camera wasn't in Device Manager), but right now I haven't both. 

Could somebody tell me what can I do? Is it possible to reset BIOS (clear, cmos) without disassembly my laptop? I wanna to avoid that.  

The simpliest way is install drivers for webcam, but I couldn't find drivers for HP Truevision HD.
