In order to see call stack on Editor crash you can run
Build MyProjectEditor Win64 Development "D:\Unreal\MyProject\MyProject.uproject" -waitmutex
this command for building your project. After that opening the project in UE4Editor will write call stack into log on editor crash. For my project it is located in D:\Unreal\MyProject\Saved\Logs\MyProject.log
Excuse my asking but how exactly do I run this? I am new to this environment.but am interested in methods for fault finding and analysis. I usually progrram microcontrollers so it is quite different.
