Can't get ".NET Desktop Runtime 5.0.5" by windows update and My Visual Studio 16.9 still install ".NET SDK 5.0.201"

[QHQuach]

I am getting below unit test execution error both in Visual Studio IDE 2019 (16.9.3) and command line through vstest.console.exe (16.9.1). This happens even after installing the latest .NET 5.0.5 (5.0.202 SDK). Any idea?

I even tried to debug into the Newtonsoft 13.0.1 but only to find the constructor just quits and throws the exception. The module runs fine during runtime.

The failing unit test project is using the following:

• xunit (2.4.1)
• xunit.runner.visualstudio (2.4.3)
• NSubstitute (4.2.2)
• mstest.testframework (2.2.3)
• Mircrosoft.NET.Test.Sdk (16.9.4)
• Microsoft.QualityTools.Testing.Fakes (16.7.4-beta.20330.2)

It is testing components/apps that are .NET Core 2.1 targeting .NET FW 4.6.2. Below is the stack trace from the unit test command line execution

Error Message:
