Unity 2020, Arrays of Seralizable will throw exception

[SmikeSix]

Hi i have something like this:

public class FoldoutSample : MonoBehaviour
    {
        public int onexx;
        [MarkedUpField(indentChildren: false, showControl: false)]
        public List<Level1_Array> LangLangM;

        [Foldout("Foldout In A Box")]
        public int one;
        public int two;
        public int three;
    }

    [MarkedUpType]
    [System.Serializable]
    public class Level1_Array
    {
        public string test;
        public string testxx;
        [ToggleGroup("Toggle Group xx xxx x")]
        public bool boolean;
        public int level1propertyInt;
    }

Also if i use on the classes
    [MarkedUpType]

It wont draw arrays/lists of seralizable marked classes and will throw an:
