MAUI Project Works on Android But Crashes on IOS - maui

Question

I have a project using RC1 of MAUI that is running fine on the Android emulator. When it runs on an emulated iOS device, it always crashes. The code in question is based in the constructor for a form. I need some code I need to run async (which you can't do in a constructor), so my code kicks it off like this:
Task.Factory.StartNew( () =>
{
AppCheck();
});
All the code is doing right now is creating a globally scoped variable's property, then setting the binding context, like this:
BindingContext = App.Status;
I get a dialog on the Mac where the emulator is running that says it "quit unexpectedly" with a bunch of crash dump details. On the Android emulator, it all just works. So looking for suggestions on what to do here, i.e. is there someplace I can or should upload the dump file, or does iOS just not deal with async code, or ??
Thanks,
Steve

VERSION 1
It might be safer to set BindingContext on Dispatcher’s thread (MainThread):
Dispatcher.Dispatch(() =>
BindingContext = ..
);
VERSION 2
If you want to use await on Main thread:
Dispatcher.Dispatch(async () =>
{
await ...;
BindingContext = ...
});
VERSION 3
If you have async code that you'd rather run on background thread:
Task.Run(async () =>
{
// On background thread.
await ...;
...
Dispatcher.Dispatch(() =>
{
// On Main thread.
BindingContext = ..
});
});
