Dell xps 13 7390 2-1 camera stopped working

I purchased the XPS13 7390 2in1 with Windows 10 Home per-installed. The camera was working just after buying the laptop. I upgraded to Windows 10 pro and after a while, the webcam stopped working. The camera app gives the error 0xA00F4244 . I restarted the laptop, checked Dell SupportAssist, and downloaded everything, uninstalled the driver, even reinstalled (clean) Windows, still nothing. I contacted Dell Technical Support and all they cared about was where "my system" is located and they referred me to some international number I can't really call. Any help?
