Using RunOaktonCommands in combination with a test using a WebApplicationFactory results in a ObjectDisposedException

I have the following program: public sealed class Program { public static async Task Main(params string[] args) { try { var builder = WebApplication.CreateBuilder(args); await using var app = builder .Build(); app.UseRequestLocalization( new RequestLocalizationOptions { DefaultRequestCulture = new RequestCulture("nl-NL"), }); await app.RunOaktonCommands(args); } catch (Exception e) { Console.WriteLine(e); throw; } } } With the following Test: public class Tests : WebApplicationFactory { protected override void ConfigureWebHost(IWebHostBuilder builder) { builder.UseEnvironment("UnitTest"); builder.ConfigureLogging(l => l.AddConsole()); } [Test] public async Task Test1() { Server.PreserveExecutionContext = true; using var client = CreateClient(); Assert.Pass(); } } This results in a failed test with the following error log:  Test1  Source: UnitTest1.cs line 17  Duration: 279 ms Message:  System.ObjectDisposedException : Cannot access a disposed object.

Using RunOaktonCommands in combination with a test using a WebApplicationFactory results in a ObjectDisposedException

I have the following program: 

public sealed class Program
{
    public static async Task Main(params string[] args)
    {
        try
        {
            var builder = WebApplication.CreateBuilder(args);

            await using var app = builder
                .Build();

            app.UseRequestLocalization(
                new RequestLocalizationOptions
                {
                    DefaultRequestCulture = new RequestCulture("nl-NL"),
                });

            await app.RunOaktonCommands(args);
        }
        catch (Exception e)
        {
            Console.WriteLine(e);
            throw;
        }

    }
}

With the following Test: 

    public class Tests : WebApplicationFactory
    {
        protected override void ConfigureWebHost(IWebHostBuilder builder)
        {
            builder.UseEnvironment("UnitTest");
            builder.ConfigureLogging(l => l.AddConsole());
        }

        [Test]
        public async Task Test1()
        {
            Server.PreserveExecutionContext = true;
            using var client = CreateClient();
            
            Assert.Pass();
        }
    }

This results in a failed test with the following error log: 

 Test1
   Source: UnitTest1.cs line 17
   Duration: 279 ms

  Message: 
System.ObjectDisposedException : Cannot access a disposed object.

                                          items

If I change "app.RunOaktonCommands(args)" into "app.RunAsync()" the unit test succeeds. So something in RunOaktonCommands is either requesting a disposed object or disposing an object prematurely.

Am I missing something, am I doing some configuration wrong, is the cause of this issue the warning by Oakton, or is this something out of my control?
