I cannot get the casualty calculator to work. I've tried running the OpenGL and the DirectX BAT files and it still will not work. I'm running off a GTX 1660 Ti.

This is strange. The GPU is new enough and should definitely be able to do the calculations.
You can try to update your drive and your DirectX to the latest versions. You can try running it as administrator. Also, if you have an onboard GPU, make sure you are running it on the dedicated High-Performance Nvidia GPU. If none of this works, please send me your Player.log file from C:\Users\<your user name>\AppData\LocalLow\Ivan Stepanov\Nuclear War Simulator to my email ivan.stepanov.nws@gmail.com
