I've searched for a couple hours, can't find any mention of this anywhere.
I'm running a Windows 10 guest OS (Windows 10 Pro 1909) with VirtualBox 6.0.18 on a macOS Catalina (10.15.3) host. I've installed the Guest Additions and Extension Pack, and I'm able to see the webcam option through Devices > Webcams > FaceTime HD Camera. I'm also, alternatively able to add the webcam through a Terminal command in macOS. This issue is that every time I try to use the camera (using the Windows Camera app), the Windows guest quits unexpectedly.
I tried updating VirtualBox to 6.1 and rolling back to a prior version as well, and the issue reoccurs. I'm not sure if this is relevant, but I would've expected to see VirtualBox allowed access to the camera through System Preferences > Security & Privacy > Privacy, but it's not listed.
Does anyone have any thoughts on this?
