媒体捕获初始化错误

我有一个问题与UWP媒体捕获初始化。我的代码如下，

private async Task StartPreviewAsync()
{
    try
    {
        //set initilize settings
        Settings oneSetting = null;
        using (SQLite.Net.SQLiteConnection conn = new SQLite.Net.SQLiteConnection(new SQLite.Net.Platform.WinRT.SQLitePlatformWinRT(), sqlpath))
        {
            oneSetting = (from p in conn.Table<Settings>()
                          where p.id == 0
                          select p).FirstOrDefault();
        }
        if (oneSetting.camera != null)
        {
            var settings = new MediaCaptureInitializationSettings();
            settings.StreamingCaptureMode = StreamingCaptureMode.Video;
            settings.PhotoCaptureSource = PhotoCaptureSource.VideoPreview;
            var devices = await Windows.Devices.Enumeration.DeviceInformation.FindAllAsync(Windows.Devices.Enumeration.DeviceClass.VideoCapture);
            foreach (var device in devices)
            {
                if ((device.Id).Equals(oneSetting.cameraId))
                {
                    settings.VideoDeviceId = device.Id;
                    break;
                }
            }
            _mediaCapture = new MediaCapture();
            await _mediaCapture.InitializeAsync(settings);
            //MediaCapture m = new MediaCapture();
            //await m.InitializeAsync();
            var focusSettings = new FocusSettings();
            focusSettings.AutoFocusRange = AutoFocusRange.FullRange;
            focusSettings.Mode = FocusMode.Auto;
            focusSettings.WaitForFocus = true;
            focusSettings.DisableDriverFallback = false;
            _mediaCapture.VideoDeviceController.FocusControl.Configure(focusSettings);
            await _mediaCapture.VideoDeviceController.ExposureControl.SetAutoAsync(true);
            _mediaCapture.SetPreviewRotation(VideoRotation.Clockwise90Degrees);
            _mediaCapture.SetRecordRotation(VideoRotation.Clockwise90Degrees);
            capturePreview.Source = _mediaCapture;
            await _mediaCapture.StartPreviewAsync();
            _isPreviewing = true;
            _displayRequest.RequestActive();
            DisplayInformation.AutoRotationPreferences = DisplayOrientations.Landscape;
        }
    }
    catch (UnauthorizedAccessException)
    {
        // This will be thrown if the user denied access to the camera in privacy settings
        System.Diagnostics.Debug.WriteLine("The app was denied access to the camera");
    }
    catch (Exception ex)
    {
        System.Diagnostics.Debug.WriteLine("MediaCapture initialization failed. {0}", ex.Message);
    }
}

返回mediaccapture初始化失败。{0}的错误。最近，它运行良好。但是从今天早上开始，它给出了错误。有人犯过同样的错误吗?

完整的错误信息是;

本系统不支持指定的设备接口级别或特性。: Media Capture初始化失败。{0}线程0x1924已经退出，代码为0 (0x0)。
