Hi.
This crash happens when I attempt to drag a anim notify in the montage editor. In my case an Audiokinetic custom event. This does not normally happen, but today is apparently “that day” and this has now crashed 6 times in a row. Normally there is like a 15% chance of crash when I drag a notify.
I do not know why the code fail to have a LastWidget, but preventing the crash should be easy. See attachment.
Enjoy.
