How Can I Debug ASP Core Controller Registered, but Not Matching?

I have started a basic ASP Core MVC project in VS. Set up a basic test controller, and visited the endpoint; but I get a 404 response status page instead. (Screenshot of ASP Debug logs attached)

How can I further debug why my controller is registered (being found with AddControllers/MapControllers) but not being selected?

Controller code is below. Screenshots of outputting the app's known controller classes attached.

using Microsoft.AspNetCore.Mvc;

namespace StripeWebhookHost.Controllers
{
    public class TestController : Controller
    {
        [HttpGet]
        public IActionResult Test()
        {
            return Content("Hello");
        }
    }
}

using Microsoft.AspNetCore.Mvc;

namespace StripeWebhookHost.Controllers
{
    public class TestController : Controller
    {
        [HttpGet]
        public IActionResult Test()
        {
            return Content("Hello");
        }
    }
}

using Microsoft.AspNetCore.Mvc;

namespace StripeWebhookHost.Controllers
{
    public class TestController : Controller
    {
        [HttpGet]
        public IActionResult Test()
        {
            return Content("Hello");
        }
    }
}

using Microsoft.AspNetCore.Mvc;

namespace StripeWebhookHost.Controllers
{
    public class TestController : Controller
    {
        [HttpGet]
        public IActionResult Test()
        {
            return Content("Hello");
        }
    }
}
