    I'm seeing this in 2022.2.17 and 2022.2.18, would love some more information in the error to track down the source of the issue.

    We're experiencing the same message (twice per play) after we installer localization package (so addressables were installed as dependency, as well).

    I also can confirm the same behavior that @fipsy and @sangemdoko experienced - I started getting these errors today when I converted the data part of one of my MonoBehaviors over to a ScriptableObject, where I have a generic list field using SerializeReference instances. I get the error message and nothing else.

    Any way to find this missing references?

    I also get this error when I have deleted a ScriptableObject that was referenced inside an object serialized via SerializeReference

    I was also able to reproduce the same error caused by a "missing object" field in an object serialized by [ReferenceSerialize] in a list of generics.
    Instead of printing a warning saying the object that has a missing reference, it prints this error with no stack trace.
    It took two people an entire day to found the culprit in my project
