Why might my cameras not be detected since install?

After initial total scan of my system the webcam is not working anymore.
Any idea ??

как включить камеру

I have a Logitech C920s webcam. Everything was working perfectly fine until Wednesday evening. At that time I started doing a bunch of maintenance within BoostSpeed. Something in my system was changed, and now I get a BSOD whenever I boot my computer when the webcam is plugged in. If I remove the webcam from the USB port, then the computer boots fine.

I've run two different anti-virus programs (including your Anti-Malware) and I also have your driver updater. Plus I made sure that I have the latest version of Logitech's LogiCapture software. And it does not appear that there were any Windows updates (other than Defender) since last week.

So...at this point I cannot use my webcam and I'm fairly certain it was due to some change made within BoostSpeed.

Please help me fix this. Is there an audit log in BoostSpeed that shows what settings were changed?

A webcam physically presents on my PC, but system cannot recognize it. I tried many apps to detect a webcam but they did not help.

Thanks in advance.
