FadeTo giving NulLReference Exception after updating to latest Xamarin.Forms

From this code:
this.label_1.Text = "test"; //Works
this.label_1.FadeTo(0, 0); //NullReferenceException

i get this message:

Exception thrown: 'System.NullReferenceException' in Xamarin.Forms.Core.dll

I created a new project to verify that nothing else was causing the problem.

This happens on in my UWP project in Visual Studio 2019, but everything works fine on Visual Studio Mac.
