Unreal Engine Issues and Bug Tracker (UE-44505)

Description

Note those are not 100% repro steps they are what I remember doing.

I've got this issue twice so far and both times I was editing a blueprint and switching between constructions script and event graph

Steps to Reproduce

Open QaGame
Open AEoverview map
Open Asset AEO_StageFloor
In the construction script select the add child actor components and set them to is editor only
Launch on windows
Load a bunch of audio levels.
Exit out of the launch on
cut all the BP logic in the construction script and paste them into the event graph
Start connecting the event begin play
Result
Editor crashed

My 2nd repro was similar to the first
The difference was at step 7 I pressed PIE, exited, closed the BP and then reopened it.
