Greetings, we have analyzed your query and we would like to inform you that this is a framework level problem. While using x:Bind with different type source and target, it will throw this exception. This problem occurs in all version of UWP not only in 1809.
You can resolve this problem by using Binding instead of x:Bind in your application as per the below code snippet.
today I updated Windows to 1809 version and I updated the destination version of my app to Windows 1809. Until yesterday I used my app with that xaml and Windows SDK 1803.

Thanks for your update, however this binding problem occurs in all the msdn control like (ContentControl, TextBlock..etc), not only in SfNumericTextBox. Please check the behavior of x:Bind markup extension in below link.
