I registered the controller path + method name (view name) but returns a 404 error. What should I do?

public void ConfigureServices(IServiceCollection services)
        {
            services.AddControllersWithViews();
            services.AddTransient<IAllCars, MockCars>();
            services.AddTransient<ICarsCategory, MockCategory>();
        }

@using WebApplication29.Data.Models 
@model IEnumerable<Car>
@{
    Layout = null;
}

<!DOCKTYPE html>

    <html>
    <head>
        <meta name="viewport" content="width=device-width"/>
        <title>List</title>
    </head>
    <body>
        <h2>Все автомобили</h2>
        @{ 
            foreach(var car in Model)
            {
                <div>
                    <h2>Модель: @car.name</h2>
                    <p>Цена: @car.price.ToString("c")</p>
                </div>
            }
        }

You misspelled startup.
https://metanit.com/sharp/aspnet5/3.6.php
Namely, they forgot to map the controllers in UseEndpoints

endpoints.MapControllerRoute(
                    name: "default",
                    pattern: "{controller=Home}/{action=Index}/{id?}");
