I recently purchased a Logitech Brio 4k UHD webcam. To test it out, I opened up the Windows Camera app, only to be met with an error message "Close other apps: It looks like another app is using the camera already. 0xA00F4243(0xC00D3704)"
I tried the basic troubleshooting steps such as reinstalling the driver, resetting the Camera app, contacting Logitech, which only resulted in escalating the case.
I also tried Finding out which app is using the webcam, using Process Explorer to determine which process is accessing the webcam, but Processor Explorer reports 0 processes using the webcam.
The webcam is somewhat functional; Windows Hello works, and the webcam is recognized by Skype, so my guess is that there is a driver compatibility issue with the latest Windows 10 update or something. Does anyone know how to resolve this error?
