Unreal Editor crashes every time I try to create a Structure

Development Programming & Scripting Blueprint
1

I can right click in a content folder, choose Blueprints > Structure, it prompts me to name the thing, and whether I leave it the default name or change it, as soon as I press Enter the editor crashes. Restarting my computer has not fixed this. I am using macOS Sierra 10.12.4 and engine 4.15.2. Has anyone else encountered this problem or know what I can do about this? Here is the crash report:

Thank you for your time.

Honestly, you should repost it on answerhub as a bug issue. Don’t take too much time for someone experienced or the Epic Staff to start helping you =)

I’m having the same issue on macOS as well, I posted a question on answerhub: Editor Crashes When Creating Structure - Programming & Scripting - Unreal Engine Forums

I am also having this issue.
It’s happened since one of the recent updates.
