Start with the C# log and the Nop.Web project mentioned in the report, especially Presentation/Nop.Web/Nop.Web.csproj and the Razor view Areas/Admin/Views/Order/List_cshtml.g.cs. Reproduce the documentSymbol, diagnostic, document pull, or codeAction failure in the reported VS Code, C# Dev Kit, .NET, and Windows environment.
