Following your steps, I was not able to recreate the crash on our end on either a Mac or PC workstation. I was able to focus on any character or asset in the World Outliner in any of the four screens.
Can you send me the dxdiag for your machine (PC), plus the callstack copy and pasted from the crash reporter?
Thanks for the additional information. While I am still not able to reproduce the issue here, I was able to locate your crashes on our Crash Reporter page which are linked to an issue that has already been reported and is currently being worked on: JIRA [UE-20579]. When this issue has been resolved, we will update this post to let you know.
