WebCamDevice.devices crash on Windows

My PC has a USB webcam device and a virtual webcam program installed, and 4 video capture boards.

Calling WebCamDevice.devices causes a crash. I suspect it is because of the virtual webcam driver or video capture board. Is there a workaround?

Is there any way to use WebCamDevice until Unity solves it?
