Question

Hello, i have a problem with FilePicker
I use this code in MainPage.xaml.cpp:
MainPage::MainPage()
InitializeComponent();
namespace nWSP = Windows::Storage::Pickers;
namespace nWS = Windows::Storage;
namespace nWSS = Windows::Storage::Streams;
auto file_picker = ref new nWSP::FileOpenPicker();
file_picker->ViewMode = nWSP::PickerViewMode::List;
file_picker->FileTypeFilter->Append(".flac");
auto var1 = create_task(file_picker->PickSingleFileAsync()).then([this](StorageFile^ file)
if (file != nullptr || file->Path != nullptr)
in choose file page when i hover with mouse over the *.flac file app is break with exception on line 58 App.g.hpp:
if (IsDebuggerPresent())
::Platform::String^ errorMessage = e->Message;
__debugbreak();
it happens when appears flyout of file preview
ErrorMessege is: "+  errorMessage 0x031f5e60 L"The remote procedure call failed.\r\n" Platform::String ^"
Screenshot of a moment when it happen:
Also, it happens even if i add or delete declaration of File Open Picker with supported file type ".flac"
How can i avoid this crash?

Hi Romka2411,
This problem seems to be not a programming issue. So we should work together to narrow down this issue, determine what the cause of the problem and redirect to appropriate forum.
Have you tested something and found the problem was caused by the k-lite codec pack? Please deleted the K-lite codec pack and tried your app again. If the app still crashes, that means your operation system may have some problems. You can find another computer
to test to see if the problem is still persisting. If your app doesn’t crash, that means the problem may cause by the codec. I would recommend you post question on K-lite codec site to ask help. This is a third-party library and it is out of our support range.
If you find something, please feel free to let me know.
