[UE5.1] Editor crashes if Prefab is assigned as ChildActor in BP

[sebi3110]

Hi there,

I can't use a prefab within a child actor.
If I assign a prefab to a child actor the editor crashes with the following log:

Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x0000000000000358

Is there a workaround?
I'd like to use prefabs on construction as well

Best regards!
