Can not get Roslyn to work with .NET 5 project

Question

After spending way too much time, I still can't make Roslyn to load simple C# project. Project source:

<Project Sdk="Microsoft.NET.Sdk">

    <PropertyGroup>
        <OutputType>Exe</OutputType>
        <TargetFramework>net5.0</TargetFramework>
    </PropertyGroup>

    <ItemGroup>
      <PackageReference Include="Microsoft.Build" Version="16.11.0" />
      <PackageReference Include="Microsoft.CodeAnalysis.CSharp.Workspaces" Version="3.11.0" />
      <PackageReference Include="Microsoft.CodeAnalysis.Workspaces.MSBuild" Version="3.11.0" />
    </ItemGroup>

</Project>

Code that is trying to load:

using System;
using Microsoft.CodeAnalysis.MSBuild;

namespace Metrics5
{
    class Program
    {
        static void Main(string[] args)
        {
            using var workspace = MSBuildWorkspace.Create();
            
            workspace.LoadMetadataForReferencedProjects = true;
            var currentProject = workspace.OpenProjectAsync(@"C:\work\Metrics5\Metrics5.csproj").Result;
            var diagnostics = workspace.Diagnostics;
                
            foreach(var diagnostic in diagnostics)
            {
                Console.WriteLine(diagnostic.Message);
            }
        }
    }
}

It says:

Msbuild failed when processing the file 'C:\work\Metrics5\Metrics5.csproj' with message: The SDK 'Microsoft.NET.Sdk' specified could not be found. C:\work\Metrics5\Metrics5.csproj

After I add MSBuildSDKsPath as environment value MSBuildSDKsPath=C:\Program Files\dotnet\sdk\5.0.301\Sdks it seems to pass that step and stuck in another:

Msbuild failed when processing the file 'C:\work\Metrics5\Metrics5.csproj' with message: The imported project "C:\work\Metrics5\bin\Debug\net5.0\Current\Microsoft.Common.props" was not found. Confirm that the expression in the Import de claration "C:\work\Metrics5\bin\Debug\net5.0\Current\Microsoft.Common.props" is correct, and that the file exists on disk. C:\Program Files\dotnet\sdk\5.0.301\Sdks\Microsoft.NET.Sdk\Sdk\Sdk.props

And from here I'm not sure how to proceed, am I missing some nuget package? Do I need to install additionally something?
