application in the device which with the damaged settings Expected behaviorWork well. The application can show the TextBlock Actual behaviorThrow the exception Regression?.NET 5 Known WorkaroundsThis is the dotnet runtime and wpf issues. As the dotnet/runtime#83764 , the CultureInfo.NumberFormat may throw IndexOutOfRangeException in dotnet runtime. And the wpf will use culture.NumberFormat.NativeDigits in HasLatinDigits, see wpf/src/Microsoft.DotNet.Wpf/src/PresentationCore/MS/internal/TextFormatting/NumberSubstitution.cs Lines 213 to 223 in 6f56d3f private static bool HasLatinDigits(CultureInfo culture) { string[] digits = culture.NumberFormat.NativeDigits; for (int i = 0; i > PresentationCore.dll!System.Windows.Markup.XmlLanguage.GetSpecificCulture() PresentationFramework.dll!MS.Internal.Text.DynamicPropertyReader.GetCultureInfo(System.Windows.DependencyObject element) PresentationFramework.dll!MS.Internal.Text.TextProperties.InitCommon(System.Windows.DependencyObject target) PresentationFramework.dll!MS.Internal.Text.TextProperties.TextProperties(System.Windows.FrameworkElement target, bool isTypographyDefaultValue) PresentationFramework.dll!System.Windows.Controls.TextBlock.GetLineProperties() PresentationFramework.dll!System.Windows.Controls.TextBlock.EnsureTextBlockCache() PresentationFramework.dll!System.Windows.Controls.TextBlock.MeasureOverride(System.Windows.Size constraint)The XmlLanguage.GetSpecificCulture will call the CultureInfo.GetCultureInfoByIetfLanguageTag to get the CultureInfo. And the CultureInfo.GetCultureInfoByIetfLanguageTag will use the user override. That is why wpf be affected by dotnet/runtime#83764 and that is why we can not use new CultureInfo("en-US", false).NumberFormat to fix this. In other words, the wpf framework will call the CultureInfo.GetCultureInfoByIetfLanguageTag and we should not change it to new CultureInfo(xx, false). And I think the client application use the user settings is reasonable behavior. And the application can handle error device settings.
