Ошибка при чтении HTTP ответа через HttpContent.ReadAsStreamAsync()

Приложение собирается под .NET 10 (под .NET 6 то же самое работает корректно)

Столкнулись с проблемой при попытке получить шаблоны сертификатов с КриптоПро УЦ 2.0. Сервер ЦР (API). Сборка 1.70.0.19.

Минимальный пример:

public static async Task Main(string[] args)
{
    var readAsString  = bool.Parse(args[0]); 

    using (var gostStore = new CpX509Store(StoreLocation.CurrentUser))
    {
        gostStore.Open(OpenFlags.ReadOnly | OpenFlags.OpenExistingOnly);

        var gostCert = gostStore.Certificates.Find(X509FindType.FindByThumbprint, "96271fdf86a81d8f5ea42139861a397b16b41976", false).First();

        var handler = new CpHttpHandler
        {
            SslOptions = new CpSslClientAuthenticationOptions
            {
                // Указываем сертификат клиента.
                ClientCertificates = new CpX509Certificate2Collection { gostCert },
            }
        };

        var client = new HttpClient(handler);

        using (var request_ = new System.Net.Http.HttpRequestMessage())
        {
            request_.Method = new System.Net.Http.HttpMethod("GET");
            request_.Headers.Accept.Add(System.Net.Http.Headers.MediaTypeWithQualityHeaderValue.Parse("application/json"));


            request_.RequestUri = new System.Uri("https://cpca2.fqdn3.local/api/ra/templates", System.UriKind.RelativeOrAbsolute);

            var response = await client.SendAsync(request_, System.Net.Http.HttpCompletionOption.ResponseHeadersRead).ConfigureAwait(false);

            if (readAsString)
            {
                var responseText = await response.Content.ReadAsStringAsync().ConfigureAwait(false);
                Console.WriteLine(responseText);
            }
            else
            {
                using (var responseStream = await response.Content.ReadAsStreamAsync().ConfigureAwait(false))
                using (var streamReader = new System.IO.StreamReader(responseStream))
                using (var jsonTextReader = new Newtonsoft.Json.JsonTextReader(streamReader))
                {

                    var serializer = Newtonsoft.Json.JsonSerializer.Create();
                    var typedBody = serializer.Deserialize(jsonTextReader);
                }
            }
        }

    }
    Console.WriteLine("end");
}

При попытке прочитать как строку var responseText = await response.Content.ReadAsStringAsync().ConfigureAwait(false); отрабатывает корректно.

При попытке десериализовывать через Newtonsoft.Json.JsonSerializer получаем ошибку:

Понимаю, что под .NET 10 поддержка пока не заявлена, но на всякий случай.
