Device can't find my built-in camera

[Yuldashev]

I opened Camera app and it showed me this following error:

"We can't find your camera
Error code 0xA00F4244"
I tried to fix it with the instructions given by HP community and Windows that I could find from internet and they didn't help.

Device Manager is not showing me the option of Camera driver.

My device is up-to-date, I even installed optional updates from Windows Update. I installed all the drivers from the HP drivers website.

And then I tried to connect with Microsoft Agents with live support chat. The agent told me that I need to install Camera driver which he couldn't find from HP drivers website. I don't even imagine how this can be fixed if the HP website doesn't have compatible driver and my laptop doesn't show it. 

Additionally, my laptop doesn't have any switching on and off camera buttons or anything like that. My camera privacy settings are enabled.

This started after I installed Camo Studio. I was talking to a friend of mine in a video call and tried to turn on my camera. My friend told me that it was showing something that said to refer to the settings in the Camo Studio app. Note that it is not a webcam

I suggest uninstalling the Camo Studio.

Try the following:

From the User manual

https://kaas.hpcloud.hp.com/pdf-public/pdf_5342544_en-US-1.pdf

"To use your camera, select the Search icon in the taskbar, type camera in the search box, and then
select Camera from the list of applications."

You might try a hardware reset. Hold the power button down for at least 15 seconds.

Drivers for webcam are at the  Windows update catalog or the manufacturer's website. You will need to know the manufacturer of the webcam.
