I have tested this on 4.13 Preview 3, it seems like it has not been solved yet. But JIRA says that it is solved Unreal Engine Issues and Bug Tracker (UE-29849)
Thank you for pointing that out ,
There have been a lot of changelists between when I verified this fix and Preview 3 so I’m fairly sure it was fixed at the time but it does seem like it may be back. I forgot to mention on the public JIRA but the fix for this was only for valid paths. If the path is invalid, the editor will still crash. Can you ensure that the path you’re using is valid?
