2D game crashing of simple code

Hey community,

I built a game based on the 2D Side Scroller example. I added my flipbooks sprites etc, nothing very complicated. Then I followed a tutorial about saving locations, since the player can place stuff and I want it saved.

Everything is running in my Character, but when I was finished UE4 crashed when I pressed PIE, and the packaged game (ETC1, game ran on Galaxy A40 which is powerful enough for my 3D Games) laggs.

The links show my code, I blurred out things which aren´t important and can´t cause this since they were there when the game ran fine.

Links don´t appear in my Preview, so if you dont see them above just paste this:
