In Unity, when SerializeField is None during scene execution, it will now output an error.

This prevents SerializeField from unintentionally becoming None.

How to allow None

• Adding the Optional attribute will exclude that SerializeField from error checking.

[SerializeField, Optional] SomeBehaviour _someBehaviour;

• By specifying namespaces and assembly names in ProjectSettings, MonoBehaviours included in the specification will be excluded from error checking.
