Can't debug NUnit tests in Rider

Hi,

I've created a new Console application in rider with .net Core 3.1 and then created a new Test project which came with NUnit.

And for some reasons, I can run the tests but I can't debug them. It either hang on "Pending" or end in "Inconclusive: Test not run".

Test project csproj:

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

    <PropertyGroup>
        <TargetFramework>netcoreapp3.1</TargetFramework>

        <IsPackable>false</IsPackable>
    </PropertyGroup>

    <ItemGroup>
        <PackageReference Include="nunit" Version="3.12.0" />
        <PackageReference Include="NUnit3TestAdapter" Version="3.17.0" />
        <PackageReference Include="Microsoft.NET.Test.Sdk" Version="16.7.1" />
    </ItemGroup>

    <ItemGroup>
      <ProjectReference Include="..\FunctionDefinitionParser\FunctionDefinitionParser.csproj" />
    </ItemGroup>

</Project>

#Test class:
namespace FunctionDefinitionParser.Tests
{
    public class Tests
    {
        [SetUp]
        public void Setup()
        {
        }

        [Test]
        public void Test_Debug()
        {
            var prout = 3;
            Assert.AreEqual(3, prout);
        }
   }
}

Seems like the dotnet process exits with an error but does not provide any relevant information...

Did anyone had to fight with this also ?

Thanks
