COMException：更新到Windows 10内部版本17134后出现错误HRESULT E_FAIL

Question

在我的Xamarin.Forms项目（目前仅支持UWP）中，我们有一个特定于平台的代码，声称可以使用条形码扫描程序。当解决方案在我的＆＃34; LocalMachine＆＃34;上运行时，这种逻辑工作正常。在Windows 10上构建 16299 。每次崩溃时都会更新到Windows 10版本 17134 并出现以下异常：

System.Runtime.InteropServices.COMException: 'Error HRESULT E_FAIL has been returned from a call to a COM component.'
Error code (0x80004005)

该等异常来自await EnableScanner（）以下行：

 private async void Initialize(object sender, RoutedEventArgs e)
    {
        // create the barcode scanner. 
        if (await CreateDefaultScannerObject())
        {
            // after successful creation, claim the scanner for exclusive use and enable it so that data reveived events are received.
            if (await ClaimScanner())
            {
                claimedScanner.ReleaseDeviceRequested += claimedScanner_ReleaseDeviceRequested;

                // after successfully claiming, attach the datareceived event handler.
                claimedScanner.DataReceived += claimedScanner_DataReceived;
                UpdateOutput(ScanningLang.DataReceivedAttached);

                claimedScanner.IsDecodeDataEnabled = true;

                if (await EnableScanner())
                    UpdateOutput(ScanningLang.ScanReady);
            }
        }
        else
        {
            UpdateOutput(ScanningLang.NoBarcodeScanner);
        }
    }

EnableScanner方法：

 private async Task<bool> EnableScanner()
    {
        if (claimedScanner == null)
            return false;

        await claimedScanner.EnableAsync();
        UpdateOutput(ScanningLang.EnabledBarcodeSuccess);

        return true;
    }
