Hey, yeah. Same here. I’m also crashing in 5.5.1.
If your actor hierarchy allows it, you might as well keep the root at the world origin and only move the component.
In my case I’ve got some actors with skeletal meshes inside of them and they’re set to be spawnable.
Moving the actual actor around with the transform gizmo crashes UE when saving or scrubbing through the timeline.
Selecting a component and moving that around with with the transform gizmo however does not crash it.
This is still a headache and a pain to work with but it is what it is.
You’re not alone. Hope that makes everyone feel a bit better. lol
