When adding a custom enumeration blueprint to a nested widget the project will crash

A user made an Enumeration blueprint that is used to reset position and to quit the game. This Enum is used in a widget by a button. The button being used is placed inside of another widget that is placed in an actor blueprint to be used as a 3D widget. If the user hits compile the project will crash with no errors showing.
