Hi;
i just trying to open a project but facing with that problem. Anyone knows how to fix it?
Could you probably post your log file (Project-Saved-Log -> should be generated right after the crash) + make sure to post it on answerhub: https://answers.unrealengine/index.html 
Also make sure to add more information (e.g which version do you use?, C++ or bp project?,…)
i just figured it out. while oculus rift was plugged in i face with that problem. now its working. thanks for quick replay.
