Windows 10: No Built-In Laptop Webcam Detected

Hi. I have been encountering problems with my Lenovo G40-70 laptop webcam after installing Windows 10 1903 on it. The webcam's driver and the section Imaging devices are missing in Device Manager, but however, I notice the Unknown USB Device (Device Descript Request Failed) in Universal Serial Bus Controller.
When I tried to access the webcam with Camera app, it says "We cannot find your camera" with error code 0xA00F4244.
I have tried different ways to fix it, manually installing drivers from my laptop brand's support site, updating and uninstalling the faulty driver but so far nothing worked.
Please help me, I have been struggling with this problem for hours and now I'm completely lost.
Here's my Device Manager list:

Windows 10 doesn't detect my built-in webcam

So, I installed Windows 10 Home a few days ago, and I've been unable to use my webcam ever since. I've taken a look at my device manager, but the webcam (it's a BisonCam NB Pro, by the way) isn't listed. I've even tried showing hidden devices, but there's
no webcam detected. There aren't "other devices" listed either. I've tried downloading the drivers for that model, but they too are unable to fine my built-in webcam. Any suggestions?

 

ASUS new laptop not detecting built-in webcam and mic

Hi

I tried your solutions but the problem still remains. The laptop does not detect the webcam at all(not listed in Device Manager). I even hard-reset the hard drive but the webcam and mic still did not work. Do you have any other possible solutions?

 

In-built webcam not detected.

Well,

me (Acer notebook user) and apparently the dell users as well ( Solved: Integrated Webcam Not working after windows 10 move - Dell Community ) are not able to get our built-in webcams running. We contact our brand supports and they tell us the same thing, update drivers,
uninstall the current ones and and install again or update the bios. NOTHING works.

The webcam appeared as hidden, with the message "Currently, this hardware device is not connected to the computer (code 45) to fix this problem, reconnect this hardware device to the computer".

Me and others have uninstalled the drivers as our support and your suggestion requests, but after restarting, the webcam is completely gone. It does not appear anyware, not even as a hidden device.

So my question is, as a reasonable person, if the webcam is apparently not connected, it means the computer does not detect any electric flow between webcam and motherboard.
The universal issue here appears to be: How can we force the flow of current between camera and motherboard?

IF it was external, it is easy, just unplug and plug in again. But, since it is a built in webcam, we cant really open our laptops ( at least it isn`t a reasonable option eventhough I could and I am sure some other as well)

P.S. It is not a drivers issue because the drivers on my notebook were up to date, and those of the people at the dell forum as well.

I would definitely appreciate a good answer
