[4.9.2] Crash when launch

Hi,

I was using Unreal with my project without problems, I then reboot my PC because other software was running bad. Once in Windows again, I launched engine with my project and it crashed instantly. It works with other projects but not with my main.

I have tried redownlading and reinstalling it, but nothing.

Here is log:
