For Unity, it seems that types containing Array and IEnumerable<> fields are not supported

[not502]

My code is very simple

public class MyTest : MonoBehaviour
{
    void Start()
    {
        var _d = new TestData() { data = Encoding.UTF8.GetBytes(\"Hello World\") };
        MemoryPackSerializer.Serialize(_d);
    }

}

[MemoryPackable]
public partial class TestData
{
    public byte[] data;
}

But running in Unity will result in the following error message

MemoryPackSerializationException: TestData is not registered in this provider.
MemoryPack.MemoryPackSerializationException.ThrowNotRegisteredInProvider (System.Type type) (at <a3c91ce317d34ad180564c2b7f9a0687>:0)

In the test, I tested three types: byte[], int[], and List<byte>, all of which resulted in the above error message. I want to know if it's due to incorrect usage or some other reason. Additionally, this issue occurs in both of my projects.

There is one more thing, I am using Unity2021.3 version (.NET Standard 2.1)
