我目前正在编写Azure认知服务教程，特别是Intent Recognition示例。当我在ConversationalLanguageUnderstandingModel上使用IntentRecognizer中的ApplyLanguageModels()方法时，我遇到了一个System.AccessViolationException。
下面是我的代码片段：

var speechConfig = SpeechConfig.FromSubscription(_speechKey, _speechRegion);
speechConfig.SpeechRecognitionLanguage = "en-US";

using var audioConfig = AudioConfig.FromDefaultMicrophoneInput();

// Creates an intent recognizer in the specified language using microphone as audio input.
using (var intentRecognizer = new IntentRecognizer(speechConfig, audioConfig))
{
    var cluModel = new ConversationalLanguageUnderstandingModel(
                                                                    _languageKey,
                                                                    _languageEndpoint,
                                                                    _cluProjectName,
                                                                    _cluDeploymentName);
    var collection = new LanguageUnderstandingModelCollection();
    collection.Add(cluModel);
    intentRecognizer.ApplyLanguageModels(collection);

错误发生在intentRecgonizer.ApplyLanguageModels(collection)，堆栈跟踪显示：

Fatal error. System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

我使用的是Azure Cognitive Services SDK版本1.28.0。（VS 2022 .NET 6控制台应用程序）
我已经检查了密钥、端点和部署名称，它们似乎都是正确的。我也试着把我的SDK更新到最新版本。然而，这些尝试都没有解决这个问题。
有没有人对这个System.AccessViolationException有任何见解或解决方案？
先谢谢你的帮助。
