Windows 10 Camera App: "Close other apps" Error 0xA00F4243(0xC00D3704)

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?

 

camera not working

If you have the camera connected to the computer, I would suggest that you disconnect the camera and then try to open the Camera app.



If the camera app opens, follow the steps below:

• Press “Windows key + C” from your keyboard to open “Charms bar”.
• Select “Settings” option.
• Select “Permissions” option.
• Turn on “Allow this app to access your: Webcam and Microphone” option.
• Lose the app by pressing “Alt key + F4” from your keyboard.
• Reopen the Camera app.
• Connect your camera and then check how this app works.

Goodluck!
