fatal error C1083
That it can’t find a specified file. What is the full error you are getting?
D:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.23.28105\include\crtdefs.h(10): fatal error C1083: Cannot open include file: ‘corecrt.h’: No such file or directory
Then it sounds like you don’t have the Universal C Runtime installed. Did you not choose the Game Development with C++ workload when installing Visual Studio?
I suggest you tick the Unreal Engine Installer option even if you already have it installed as that will install all required dependencies.
