Unreal really does not like your sniper rifle blueprint in particular and they are broken in my project as well. I am going to create a new project and try them there I guess. When I hit ‘play’ and say yes to ignoring the sniper rifle error I cannot get any UI to appear 
What version of unreal did you build the project in? I will download that version and try.
