I followed the instructions on A new, community-hosted Unreal Engine Wiki - Announcements - Epic Developer Community Forums to install UE4.18 on Ubuntu16.04. I chose version 4.18 to avoid possible imcompatible problems running a project created with UE4.18.
CPU: i7-6700K CPU @ 4.00GHz × 8
GPU: NVIDIA Corporation GM204GL [Quadro M4000] (rev a1)
It had been going perfectly well before I ran into the crashing problem when finally running it (./Engine/Binaries/Linux/UE4Editor). It crashed as soon as the loading of UE had been finished. I googled and retried several times but it still crashes. Here are the important lines I think (with two warnings in the middle but no error):
