Default routing issue in ASP.Net Core 3.1 MVC

Question

I have an ASP.Net Core 3.1 MVC project running at https://localhost:5006 using default routing.

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

If I browse to https://localhost:5006/Home/Index or even https://localhost:5006/Home, it works as expected. (The Index action of the Home controller is executed.)

But when I browse to https://localhost:5006, I get a blank page in the browser.

Looking at the logs (pasted below), Routing.EndpointMiddleware (or any other middleware) seems to not be running on the request to '/' (like it is on the call to '/Home'. Any ideas of what to look at next to debug this?

Here is output from the Kestrel console:

First Request
