Resolution Note (fix version 2021.2):
When a base class has many fields of a derived class, that are being serialized by-value, then this recursive definition can cause an long delay and out of memory crash. The fix will detect such a recursive definition and not serialize the field, just as fields inside a class are not serialized if they have the class as their type. ScriptableObjects or [SerializeReference] should be used instead of by-value serialization for this sort of data structure design.
