It seems that the constructor of NavMeshPath apparently has code that can’t run OnAfterDeserialize. I have modified the instance generation so that it try/catches any exceptions (such as this) when constructing an object and attached the changed for you here.
This will at least prevent the NavMeshPath (or other object construction that throws an exception) from being constructed if not able, but won’t go boom on the rest of the graph.
