Resolution Note:
This is an issue in the package UnityFx.Outline.
During pre-filtering, we try to walk the fields of classes, we end up trying to walk OutlineLayerCollection as an enumerable, however this class has a null list internally and does not safeguard against and the package code crashes trying to get the enumerable from its own list.
There is not a way we can safeguard against this as we can't know the internals of their interface implementation. The list seems to be null because the "Outline Layers" field on their render pipeline asset is "Missing".
