Build an ios app from windows with the Microsoft.Appcenter nuget crash on run

[softlion]

Hey :)
I tried to start my app on an iOS simulator.
It is a maui android+ios app, and i'm using VS Preview on windows.

The app build ok, it starts, but it crashes directly on an AppCenter call.

Any clue ?

System.TypeInitializationException: The type initializer for 'Microsoft.AppCenter.Utils.ApplicationLifecycleHelperDesktop' threw an exception.
 ---> System.IO.FileNotFoundException: Could not load file or assembly 'System.Windows.Forms, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies.

It gives me the same error when compiling an application from Windows to iOS (MAUI).

We saw the same exception when starting iOS on MAUI using the Microsoft.AppCenter v4.5.3 NuGet. Updating to v5.0.1 resolved the issue.

Yes, this works for me as well. I think we can consider this fixed.
