Hi, good day!
When you open the Camera app, what exactly happens? Do you see an error message such as 0xA00F4244 or 0xA00F4243, a black screen, or does the app not open at all?
Also, please check Device Manager
Press Windows key + X and select Device Manager.
Expand Cameras or Imaging devices
Is your integrated camera listed there? If so, is there a yellow warning icon next to it?
I look forward to your update and am willing to collaborate with you until we resolve the issue. Keep me posted by clicking "Add comments" below.
