Hello, UE4 team and game developers.
I’m currently working on Unreal Engine project using version 4.18.3
Editing and compiling Blueprint has no problems and works well.
But when I add c++ code and compile, then the unreal editor crashes and terminate at the end of the compile process.
I switched visual studio version to 2015 from 2017, but it didn’t help me.
The problem is that when I restart the unreal editor after crashing, second compile succeed soon.
So I’m so tedious about restarting the unreal editor every time I added new c++ code and compile.
Compiling without code change always success, but always crash when I put any small c++ code.
My project currently contains MobileUtils, Gamesparks, Crashlytics plugins included.
Please give me the solution.
I found the developers encountered same issue but I cannot find the proper answer or solution.
Please help me and tell me the solution if you have.
Thank you.
Can you pls upload log + crashdumps? 
Without that even Neo from Matrix cant debug this
