C++ Adding Objects to List Run time Error

Question

My Game.cpp function init throws run time error while adding objects to a list. I have the console print message before and after the place of error for debugging. main.cpp creates Game object and calls function init() which creates objects and a list. The function should add them to the list. There are no compile errors and I had this working on what seems identical project. We should expect the message "Items Start Adding" to print before the adding to list and "Items Added" to print afterwards. This would let us know they have been added. I have added the error image below that I get and it seems to open up the list class and point to a exact line of issue in the list class

Thanks
