The UWP platform is quite new, but it works very well, and Microsoft relies heavily on it. With the power of .NET Core and XAML, it helps developers create applications for Windows 10 that are more modern, beautiful and responsive. But in the end, it’s software that runs on a computer and can have bugs. It’s no big deal. One of these bugs is Windows.UI.Xaml.Markup.XamlParseException UWP App Error. This can happen with any universal Windows application and, as far as I know, it is caused by an XAML analysis error.
This is a XAML problem, and if you look at it carefully, it tells you that there is a place in XAML where you assign a value to “FontFamily” and the value is empty. This may be due to linking or direct assignment of blank values or animation. Such things can be in Page XAML or Styles (most likely StandardStyles.xaml).
