I think this is an issue with the protocol activation which just seems to be entirely broken. There is/was #979 but that didn't get far :/

Correct, we should be using the new APIs introduced for WinAppSDK: https://learn.microsoft.com/en-us/windows/windows-app-sdk/api/winrt/microsoft.windows.applifecycle.appinstance.getactivatedeventargs?view=windows-app-sdk-1.3#microsoft-windows-applifecycle-appinstance-getactivatedeventargs

var eventargs = Microsoft.Windows.AppLifecycle.AppInstance.GetCurrent().GetActivatedEventArgs();

if (eventargs.Kind is ExtendedActivationKind.Protocol && eventargs.Data is ProtocolActivatedEventArgs)
{
      ProtocolActivatedEventArgs ProtocolArgs = eventargs.Data as ProtocolActivatedEventArgs;
      var uri = ProtocolArgs.Uri;
}
