The reason it is vanishing from your animated camera view when you turn it 3d is because it goes to the default position… a place your camera no longer is. It’s a quick fix though.

when you make the layer 3d, select the layer and hit P to bring up it’s position coordinates. Then, select your CAMERA and hit A to bring up the camera’s point of interest coordinates. Then all you have to do is CTRL C (copy)the camera’s Point of Interest and CTRL V (paste) it into the 3d layers Position. That should bring it back into camera view for ya. Hope that helps.
