How do I solve blank screen while sharing the display by ViewBoard Cast after upgraded MacOS to 10.15.2?

Please setup your MacOS 10.15.2 at the path below to get the vCastSender app “Screen Recording” authorized, then reboot the Mac device. 

 

Path: System Preferences > Security & Privacy > Privacy > Screen Recording > vCastSender
