Xamarin iOS Crash on Launch mono_handle_exception_internal mini-exceptions.c EXC_BAD_ACCESS (SIGABRT)

Question

When I submit the app to the AppStore, I get an error from Apple, can I ask a question here

After a while trying to read the crashlog file Apple attached (I use AppCenter) to see it. I get error content like this:

mono_handle_exception_internal
mini-exceptions.c, line 2791
EXC_BAD_ACCESS (SIGABRT)

I don't know what that error means. I can only view the file Main.cs

static void Main(string[] args)
{
    // if you want to use a different Application Delegate class from "AppDelegate"
    UIApplication.Main(args, null, typeof(AppDelegate));
}

I searched for related keywords: mono_handle_exception_internal, but no match was found. Looking forward to everyone's help.

Update

protected override void OnAppearing()
{
    base.OnAppearing();

    var statusbar = DependencyService.Get<IStatusBarPlatformSpecific>();
    statusbar.SetStatusBarColor(Color.FromHex("f1f1f1"));
}

IStatusBarPlatformSpecific.cs

public interface IStatusBarPlatformSpecific
{
    void SetStatusBarColor(Color color);
}
