It’s very simple to reproduce:
Add Spawn Actor From Class.
Add variables of class PostProcessVolume.
In variable set default value to PostProcessVolume.
After Spawn Actor from class add Cast to PostProcessVolume.
Then from Cast use Set Settings.
Make settings.
And there is property Blendables of type objects. If there is nothing in, it won’t compile, because it needs array of objects variable.
So create array, plug in, and… Crash!
