After launching Unreal Engine from the Unreal Launcher the editor will come up briefly (20-30s), behave normally, then suddenly crash. Looking in the logs, I am getting the following:

Try rebuilding the engine from source. You can download it online from Epic Games’s github page I think. Also, are you trying to open a certain project when it crashes? Have you tried creating a new project (an empty one) and opening it?
