      Simple repro:

      var filter = Builders<ClassWithBsonTypes>.Filter.Eq(o => o.BsonDocument.ElementCount, 1);
filter.Render(new(BsonSerializer.SerializerRegistry.GetSerializer<ClassWithBsonTypes>(), BsonSerializer.SerializerRegistry));

public class ClassWithBsonTypes
{
    public BsonDocument BsonDocument { get; set; }
}

      fails with:
      System.ArgumentException: Serializer value type MongoDB.Bson.BsonValue is incompatible with expression value type System.Int32 (Parameter 'serializer')
