Hey, so I had the same problem (same log file, same crashes, same everything). I tried re-installing the entire engine launcher and all to no avail. I was about to re-install windows when I read my project’s log again. I found that I was getting errors similar to this thread. The fix suggested (deleting C:/ProgramData/Epic/Engine/DerivedDataCache/Boot.ddc) did nothing to improving my situation, but removing C:\Users\USERNAME\AppData\Local\UnrealEngine\4.1\DerivedDataCache\Boot.ddc got my editor open again after 4 hours of frustration.
Hope this helps!
