I am trying to build my first multiplayer game. I am using Advanced Sessions plugin and the steam system script on the UE4 forums.
The program works perfectly when it is in the editor, but there are issues when I try to package it.
Here is my output log after trying to package in windows 64:

Below are attached screenshots of my code. The first is the level blueprint that has the main menu widget.
The second is the main menu widget that creates a session and joins it.
