While I'm not quite sure why the screen is going dark, I can offer a different way to go about this.

In your EnemyBehavior, change the collision check to:

if(Sup.ArcadePhysics2D.collides(this.actor.arcadeBody2D, Sup.getActor("Player").arcadeBody2D)
{
        Sup.getActor("Player").getBehavior(PlayerBehavior).LowerHealth(1);
}

You can then remove

public playerCol = this.actor.arcadeBody2D;

from your PlayerBehavior.

In the future, you can usually just call whatever component you need [ arcadeBody, camera, spriteRenderer, etc. ] directly with:

Sup.getActor('Name Of Actor').NameOfComponent

Hope this helps!
