to clarify, here's the thing you need to put in Fallout4.ini for a crash log. paste this under the [Papyrus] category, or change the last 3 lines (bEnableLogging, bEnableTrace, bLoadDebugInformation) to =1:
if the system is the same as Skyrim (which it should be), there should be a Logs file with the crash log made in the Documents-->My Games-->Fallout4 file
