I looked up the software available for your laptop and did not see a webcam driver which makes it difficult to fix the problem easily.

Have you run diagnostics?
Tap the ESC key after powering on. . Tap it once a second after you see the LEDs on the keyboard flash. When you see the startup menu, press F2 to run diagnostics.

if the WebCam passed diagnostics ---

1 - enter "camera" in the windows search box. An error message may appear. If so, click "Get Help". If there is no "Get Help" then read this article.

2 - Look at the keyboard function keys for a camera icon such as

if you see anything like that the press it and see if the camera starts working. It could also be a physical device such as a switch or a cover that closes over the lens. Some AIOs have an On Screen Display and that might have camera control for on/off. I do not have your particular system so am guessing.

3 - Try a repair of windows system files. From the administrator command prompt enter as explained below

SFC /scannow

How to use SFC or DISM to repair Windows

just do the SFC. If you see a message that corrupted files were fixed then reboot. The only time to do the DISM is if the SFC reports it found problems but cannot repair it.

4 - Did this happen recently, like just after a windows update?

Try rolling back the driver
Did you try rolling back the camera driver?

It could be the camera driver or the USB driver if the camera is connected to the USB. Many internal cameras are connected to the USB.

In the pictures below you would select the camera driver and then look for 'rollback'

If camera driver is the problem

If the problem is the wrong USB driver for the camera

If you cannot rollback the driver then try to find the best one or let windows try. One way is to just uninstall the camera and reboot as described in this official HP document..

The below post, unfortunately, is complicated but is useful if there is no camera drivers at the HP website to download.
