When start in dark mode, get NullReferenceException in PlatformConfigurationExtensions.cs

By default in my xamarin forms app I have

     AppCompatDelegate.DefaultNightMode =AppCompatDelegate.ModeNightNo;

But when I start it in dark mode I get the following exception

enter image description here,

in Xamarin.Forms.Platform.Android\PlatformConfigurationExtensions.cs

System.NullReferenceException:'Object reference not set to an instance of an object.' Stacktrace: at Xamarin.Forms.Platform.Android.PlatformConfigurationExtensions.OnThisPlatform[T] (T element) [0x00000] in D:\a\1\s\Xamarin.Forms.Platform.Android\PlatformConfigurationExtensions.cs:8 at Xamarin.Forms.Platform.Android.AppCompat.FragmentContainer.OnResume () [0x00007] in D:\a\1\s\Xamarin.Forms.Platform.Android\AppCompat\FragmentContainer.cs:126 at AndroidX.Fragment.App.Fragment.n_OnResume (System.IntPtr jnienv, System.IntPtr native__this) [0x00008] in D:\a\1\s\generated\androidx.fragment.fragment\obj\Release\monoandroid9.0\generated\src\AndroidX.Fragment.App.Fragment.cs:2548 at (wrapper dynamic-method) Android.Runtime.DynamicMethodNameCounter.115(intptr,intptr)

It only happens in dark mode, in light mode it init normally. I was trying to debug but all the threads at that moment are executing external code
