Packaged Game fails with Access Violation

Hey guys,
after packaging my game it immediately crashes everytime I try to start it.
I have no problems running the game in the Editor.
The log and files don’t say anything either except that I had a Access Violation.

Here you can find the log file.

I’m using Unreal Engine 4.18.3 and an Nvidia GTX 960M

Thanks in advance for you answers
