Sorry above error is something else. I have found above error message in my appcenter logs.

Another error on size changed is thrown on UWP. Both errors are on UWP. 

System.NullReferenceException

  HResult=0x80004003

  Message=Object reference not set to an instance of an object.

  Source=Syncfusion.SfRating.XForms.UWP

  StackTrace:

   at Syncfusion.SfRating.XForms.UWP.SfRatingRenderer.Rating_SizeChanged(Object sender, EventArgs e)
