Change property in async method in WinUI3 project will throw COMException

[XFEstudio]

Here's my property

    [ObservableProperty]
    private bool isProgressRingVisible = true;

When I change it in async method

    private async void NavigationParameterService_ParameterChange(object? sender, BlueprintInfoViewData e)
    {
        await Task.Run(() =>
        {
            currentDefinitions = SpaceEngineerDefinitions.Load<MyObjectBuilder_Definitions>(e.FilePath);
            currentBlueprint = currentDefinitions.ShipBlueprints[0];
            IsProgressRingVisible = false;
        });
    }

It will throw an exception: System.Runtime.InteropServices.COMException.

OnPropertyChanged(global::CommunityToolkit.Mvvm.ComponentModel.__Internals.__KnownINotifyPropertyChangedArgs.AuthorName);

You can bypass this by moving that to your ViewModel, create a Task and mark it as RelayCommand:

[RelayCommand]
async Task MyAsyncTask(){
     -- Your code
    IsProgressRingVisible = false;
}

private async void NavigationParameterService_ParameterChange(object? sender, BlueprintInfoViewData e){
    ViewModel.MyAsyncTaskCommand.Execute(null) //Params if needed)
}
