NullReferenceException when Debug NUnit test

[PiotrNestor]

Issue Description

In a NUnit test project for Petstore API The API client is generated with NSwagStudio from the Petstore API Json definition.

Running 'Debug' results in NullReferenceException in OmniSharp.DotNetTest.VSTestManager.DebugGetStartInfoAsync

The test project Petstore.zip

Steps to Reproduce

Test example:

using System.Threading.Tasks;

namespace Tests;

public class Tests
{
    Client client;

    [SetUp]
    public void Setup()
    {
        client = new Petstore.Client(new System.Net.Http.HttpClient());
        client.BaseUrl = "http://localhost/v2";
    }

    [TestCase(TestName = "Petstore_GetInventory")]
    public async Task GetInventory()
    {
        var result = await client.GetInventoryAsync();
        Assert.That(result.Count, Is.Not.Zero);
    }
}

1. 'Debug' test GetInventory
2. OmniSharp TestManager fails

Expected Behavior

It should be possible to debug / run the test

Actual Behavior
