My problem sounds similar. It is not exactly the same. When I try to let the system build for me, it tells me witch plugins are having problems. Try disable all plugins on your ProjectName.uproject file. Start with the ones that it tells you are the problem. Then disable all of them if that does not work. Then just let ue start and rebuild the project through the normal start menu. After it starts once enable all the plugins you disabled. I had to get rid of instances in my level that were part of the plugin I disabled(crash). I saw this on a post or video a while back.
