The case is reproducible (but might not be limited to) in a dedicated environment including Windows 10, JustMock R3.2021, Visual Studio 2019 and .NET 5. When the profiler is enabled the Visual Studio has problems with the test discovery and reports "Stack overflow" exception. The same applies to building solutions with Azure Function project.
