Unity windows phone game crashes on scene load

I have a scene which has around 10 prefabs being intantiated at start. When I switch from the previous scene to this one the game crashes. I have no idea why. I tried debugging mode in Visual Studio, but it was no help. This is the output log.

I tried disabling the instantiation of the objects and building it again. No change it is exactly the same. Crashes. It used to work before and I haven't changed any settings as far as I remember.
