This issue was caused due to a version mismatch of the Microsoft.Windows.Compatibility dependency.
The potential fix will resolve the Microsoft.Windows.Compatibility dependency automatically when using the Telerik UI for WPF NuGet packages.
When referencing the assemblies directly, users need to explicitly add a package reference to the respective Microsoft.Windows.Compatibility package if they use .NET Core 3.1 or a later version. For example - 6.0.0 when targeting .NET 6, 5.0.0 when targeting .NET 5 etc.:
<ItemGroup>
<PackageReference Include="Telerik.Windows.Controls.for.Wpf.Xaml" Version="2022.2.511" />
<PackageReference Include="Telerik.Windows.Controls.FileDialogs.for.Wpf.Xaml" Version="2022.2.511" />
<PackageReference Include="Telerik.Windows.Controls.GridView.for.Wpf.Xaml" Version="2022.2.511" />
<PackageReference Include="Telerik.Windows.Controls.Input.for.Wpf.Xaml" Version="2022.2.511" />
<PackageReference Include="Telerik.Windows.Controls.Navigation.for.Wpf.Xaml" Version="2022.2.511" />
<PackageReference Include="Telerik.Windows.Data.for.Wpf.Xaml" Version="2022.2.511" />
<PackageReference Include="Microsoft.Windows.Compatibility" Version="6.0.0" />
</ItemGroup>
