No camera after compilation

Vuforia SDK Version: 8.5.9 - Description with steps to reproduce: Hello! I'm not shure, what it is a bug, but, however, i don't have a way to solve my issue. I created a primitive AR application, but i have a problem with cmpilation. This a short description: Application use a camera to place a "children image" in plane. In scene there is a VideoPlayer in the NearPlane ARcamera, but it have a cut whith alpha channel. The image from the camera (which is behind the VideoPlayer) gets into this hole. So, in editor it's work correctly, dut after building I have a blackscreen image instead. And I know, what a Camera in my laptop is not active during the application "ON". This is question: How to fix it? P.S.: I have not a target in scene P.S.S: The application must work under Windows - Development OS (Mac OS X, Windows, Linux): Windows - Mobile OS and Version: Windows - Mobile Device Manufacturer and Model name: Lenovo - Do the Vuforia Sample Applications show the same behavior?:
