Running 4.13 on a new project with the Third Person example, if i go into the default ThirdPerson_AnimBP and in the view port Preview window and click on show>Uncompressed Animations or NonRetargeted Animations the editor will crash.
Hello,
This was a known issue that was reported as fixed, but seems to be occurring again. As such I have reopened the ticket, and you can track it here: Unreal Engine Issues and Bug Tracker (UE-32715)
Have a great day
