I had the same issue, different module, same error. i did a Clean followed by a Build (completely rebuild engine from scratch) and it then allowed me to start the editor successfully.
Thanks, I did that too eventually but still didn’t help me 
Are you downloading the engine via the from or via a Git client of some kind? I’m using Source Tree to download it. Done it twice now, both times to no avail.
The editor itself seems to start, I can create new projects just fine. It’s only when I try to load my game with it that the module unloads itself during startup - but still makes no sense. I find it odd that both the Launcher and the Source version do it to me.
