.NET MAUI app crashing on startup, apparently with an error in DirectUI::PointerAnimationUsingKeyFrames

Jim Chapman 11

I am an app developer, working with .NET MAUI.

I have a .NET MAUI app published in the store, at **ms-windows-store://pdp/?productid=9WZDNCRFJ43B **which, for some users, is consistently crashing during startup, apparently in a call to ctl::ComObjectDirectUI::PointerAnimationUsingKeyFrames::NonDelegatingQueryInterface(const _GUID &, void * *). There are many crash reports in the Partner Center/Health reports list, and I can also provide a DMP file, which a user has sent me. I cannot reproduce this error on my test/development setup, but it is impacting a significant number of users. I note that error reports are coming from various different processor architectures and different versions of Windows.

Please advise regarding what changes I might make in my code, or build options, in order to address this issue.

Here is an extract of the stack trace from the DMP file that I mentioned:

coreclr.dll!EEPolicy::HandleFatalError(unsigned int exitCode, unsigned __int64 address, const wchar_t * pszMessage, _EXCEPTION_POINTERS * pExceptionInfo, const wchar_t * errorSource, const wchar_t * argExceptionString) Line 777 C++ coreclr.dll!ProcessCLRException(_EXCEPTION_RECORD * pExceptionRecord, void * pEstablisherFrame, _CONTEXT * pContextRecord, _DISPATCHER_CONTEXT * pDispatcherContext) Line 1066 C++

[External Code] Microsoft.ui.xaml.dll!DirectUI::Window::QueryInterfaceImpl(const _GUID & iid, void * * ppObject) Line 811 C++

[External Code] Microsoft.ui.xaml.dll!ctl::ComObjectDirectUI::PointerAnimationUsingKeyFrames::NonDelegatingQueryInterface(const _GUID & iid, void * * ppValue) Line 30 C++

If you need further information, please let me know.

Thanks,

Jim

Could you share the detailed Windows version and MAUI version? Do you set up some packages during startup?

Hi, thank you for responding. The crash is coming up on multiple versions of Windows (according to what I see on the Microsoft Partner Center/Insights/Health report screen). Recent crash dumps come from 10.0.26100,10.0.22635 and10.0.22631, but there are other versions impacted.

The app is built using .Net Maui 8.0.92.

As for package setup during start-up, yes, there is some initial configuration. For instance, in MauiProgram.CreateMauiApp, I call:

var builder = MauiApp.CreateBuilder(); builder .UseMauiApp<App>() .UseSkiaSharp() .UseMauiCommunityToolkit() .UseMauiCommunityToolkitMediaElement() .UseMauiCommunityToolkitCore() .UseMauiCommunityToolkitMarkup() .ConfigureFonts(fonts => { fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular"); fonts.AddFont("OpenSans-Semibold.ttf", "OpenSansSemibold"); fonts.AddFont("FiraMono-Regular.ttf", "FiraMonoRegular"); fonts.AddFont("FluentSystemIcons-Regular.ttf", "FluentSystemIcons-Regular"); });

But I'd note that, looking at the DMP file and the available stack traces, I do not see any user code on the stack, at the point when the crash happens.

Would you like me to share the DMP file? If so, should I attach it here, or send it somewhere else?
