Built-in camera not detected by the system

[Martinsim53]

My built-in camera is not detected by Windows. (0xA00f4244) However, when I insert an external USB camera, it works seamlessly. Firstly, I noticed in the device manager that the driver says the device is disconnected (it was greyed out). How could a built-in camera be disconnected, I asked. i tried everything. From the basic solutions, like privacy settings, checking for a physical switch (I do not have one), doing a system scan, nothing helped. So, I tried to reinstall the driver by deleting it, but it didn´t install back up. I even tried to check BIOS - nothing there related to camera. So, I did a factory reset (somehow it ended up on the latest version of windows, instead of the 21H2, which is the version I bought the laptop with). I even went to HP website to install the camera driver, but I haven´t found it there. I suppose there is some physical damage done on it, but I do not remember dropping or damaging my laptop in any way. Perhaps, BEFORE the reset, I was tweaking the registry, then I wanted to revert it, so I loaded a backup of the registry made just before the changes. Surprisingly, my graphics driver stopped working (NVIDIA), but reinstallation fixed it. Maybe the registry might be the issue? But as I said, I made a system restore recently, therefore I do not suspect it to be the issue. Judging by the fact that after the restore the system did not even install the driver, I am convinced it does not even notice, or recognise the camera.
