UE 4.10 crashes when building with Visual Studio 2015

Hey there,
I have recently updated to Unreal Engine 4.10. I am using Visual Studio 2015.

I normally use visual studio to build my project, using the ‘build’ command. however (this has happened twice now) sometimes when I build, Unreal crashes. The build is successful when this happens. Then, I am unable to reopen my project unless I delete all the code I updated since my last successful build, and rebuild the project.

here is the error I get when unreal crashes, and when I try to reopen my project:

Unknown exception - code 00000001 (first/second chance not available)

Let me know if you need any more info.

Also, here is the code where it crashes:

**APlayerCamera::APlayerCamera()
{
// Set this pawn to call Tick() every frame. You can turn this off to improve performance if you don’t need it.
PrimaryActorTick.bCanEverTick = true;

//Create a dummy root component.
RootComponent = CreateDefaultSubobject<USceneComponent>(TEXT("Base"));

APlayerCamera::InitializeCameraComponent(FRotator(-45,0,0));
APlayerCamera::InitializeCameraComponent(FRotator(-225, 0, 0));

CameraMoveSpeed = 200; //Initialize basic movement speed.

//Set the base actor rotation for an isometric view.
SetActorRelativeRotation(FRotator(0.f, 45.f, 0.f));

//Disable collisions.
SetActorEnableCollision(false);

//Initialize the movement component.
APlayerCamera::InitializeMovementComponent();

AutoPossessPlayer = EAutoReceiveInput::Player0;

}**

if you see i make two calls to initializecameracomponent, because I want to add two cameras to my object. If i call it once, no crash. If i call it twice, crash and project corruption.
