MONO interpreter: NIY encountered in method MemoryPack.IMemoryPackable.Deserialize

[thedude61636]

Greetings, First off You have a great package and it's really fast. However I'm getting an issue in blazor wasm with a certain object I have Currently the object has 74 fields, as soon as I add four more it crashes on deserialization on the browser in release mode and only in release mode.

MONO interpreter: NIY encountered in method MemoryPack.IMemoryPackable<Shared.Models.Main.MainModel>.Deserialize
logging.ts:119  
Error: [MONO] * Assertion: should not be reached at /__w/1/s/src/mono/mono/mini/interp/interp.c:3850

these are the fields I have I've omitted the names

I've noticed if i remove a string it stops crashing but if i remove a byte it still crashes. the exact object i'm serializing and deserializing is DataResponse<List<MainModel>> and this is the class for it

[MemoryPackable]
public partial class DataResponse<T>
{
    public DataResponse(T data)
    {
        Data = data;
    }

    public T Data { get; set; }
    public long? Result { get; set; }
    public string? ResultText { get; set; }
}

it was working fine until I added two strings and two longs if I remove any of them it works but if I remove a byte it still crashes the some of the fields have attributes [Display] and [JsonIgnore] and a custom attribute called [Order] I don't think it matters but I thought I should mention anyway
