Unreal UE4 version 4.15 and LEAP Motion Crashing when Running Standalone Game

When I enable the LEAP Plugin and Add it to a UE4 4.15 Project and Launch it as a Standalone game,
I get this error.

I do not get an Error if I run it in Preview Mode. Only when I try to Build the Deployable Game.

I have tried this on multiple computers.
I have started with Blank Projects.
As Soon as I add a Leap Enabled Character, even the Default ones with the Plugin, I can no longer Build a Windows Deployable Standalone using the Launch Button in UE4 4.15

If I remove leap enabled pawn from the Default Pawn Class setting in the Game Mode. It will compile.

This works fine in UE4 4.14

Please help!
This is Killing my Project right now.

I have included all errors I can Find.

I did find a work around.
If you uncheck the “Event Driven Loader Enabled” it will not crash, but it will throw an error about loading DamageTypes.
