Windows Build failed without any error message

I was trying to build my game on Windows 64 bit. The cook took me literally at least 30 hours(1,5 days), and eventually it failed. I have a freshly installed the latest stable version of Windows 10 with all dependencies installed, plus Unreal.
And on top of that, I waited 30 hours for nothing, because after the failed build, it deleted all the cooked content for some reason…

I hope somebody can help me resolve this thing, because I can’t afford experimenting, and letting the PC run another 100 hours of build…

Thanks in advance!
