[BUG] Self reference decorated with BsonRef results in access violation error

[JoAnnP38]

Version
LiteDB 5.0.13 / .NET 7.0

Describe the bug
A simple class with an integer id and an array of objects of the same type decorated with the [BsonRef] attribute results in an OS access violation when trying to retrieve the collection.

Code to Reproduce

    public class Weights
    {
        public int Id { get; set; } = 0;

        // comment out [BsonRef] and the the test works
        [BsonRef("weights")]
        public Weights[] Parents { get; set; }


        public Weights(int id, Weights[] parents)
        {
            Id = id;
            Parents = parents;
        }

        public Weights()
        {
            Id = 0;
            Parents = Array.Empty<Weights>();
        }

        public static Weights Get()
        {
            using (var db = new LiteDatabase("test.db"))
            {
                var c = db.GetCollection<Weights>("weights");
                Weights? w = c.FindOne(x => true);
                if (w != null)
                {
                    return w;
                }

                w = new Weights();
                c.Insert(w);
                return w;
            }
        }

Expected behavior
No access violation would be nice as it causes the OS to terminate the application. If self-references are not supported, please make it clear in the available docs.

Additional context
This error does not cause current issues for my project because I can work around it. But I would like to have this work since without this feature I cannot represent the schema of my parent/child relationship.

Can confirm it's a bug. StackOverflow actually when it try get collection.
It start call infinity round here in GetEntityMapper:
https://github.com/mbdavid/LiteDB/blob/94473353f372c725d8266f78a00588ec37121931/LiteDB/Client/Mapper/BsonMapper.cs#L244
Then in BuildEntityMapper
https://github.com/mbdavid/LiteDB/blob/94473353f372c725d8266f78a00588ec37121931/LiteDB/Client/Mapper/BsonMapper.cs#L324
And it goes in loop
