Hi,
I couldn’t package a shipping build for my game using steam on ue4.13.2 and came to this thread multiple times hoping for help. After must frustration I managed to work out what logs and error messages wanted me to do.
steam online subsystem couldn’t compile because I hadn’t installed correct visual studio packages. I had to rerun VS2015 Community installer and install “Common Tools for Visual C++ 2015”. Everything seems to work fine now and my UE4 no longer crashes during packaging.
Hope this helps someone.
