I get this issue when playing in an EXE.
Whether a zoom out is required seems to depend on the hair. I haven’t hit this issue with all hairs, but the distance seems to depend on the hair. With some hair, about 5 yards from the starting camera is enough for my game to crash on launch.
I’m not sure why this works, but for some reason, hiding the MetaHuman and immediatley unhiding it fixes something.
To do this, add two SetActorHiddenInGame nodes at the end of the BeginPlay event in each MetaHuman’s event graph. Have New hidden checked in the first node and unchecked in the second.
In the past I used SetVisibility nodes instead of SetActorHiddenInGame, with Propagate to Children checked. Unfortunately, in the latest version of Unreal, that makes some of my MetaHuman hair turn into what looks like giant red afros.
