Asp.net core application getting error : This localhost page can’t be found

Question

getting this error : This localhost page can’t be found

I am working on ASP.Net core application and were working fine but after adding Scaffolded for Identity I am getting this error ' This localhost page can’t be found' . I noticed scaffolding Identity added the below configuration in program.cs and if I comment this out it then it works fine.

builder.Services.AddDefaultIdentity<IdentityUser>() .AddEntityFrameworkStores<ApplicationDbContext>();

Below is full program.cs code

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.
builder.Services.AddControllersWithViews();
builder.Services.AddDbContext<ApplicationDbContext>(options => 
options.UseSqlServer(
builder.Configuration.GetConnectionString("DefaultConnection")
));
builder.Services.AddDefaultIdentity<IdentityUser>()
.AddEntityFrameworkStores<ApplicationDbContext>(); 

builder.Services.AddScoped<IUnitOfWork, UnitOfWork>();


var app = builder.Build();

// Configure the HTTP request pipeline.
if (!app.Environment.IsDevelopment())
{
app.UseExceptionHandler("/Home/Error");
// The default HSTS value is 30 days. You may want to change this 
for production scenarios, see https://aka.ms/aspnetcore-hsts.
app.UseHsts();
}

app.UseHttpsRedirection();
app.UseStaticFiles();

app.UseRouting();
app.UseAuthentication();
app.UseAuthorization();

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

app.Run();

I have same issue, fixed with adding area attribute on controller:

[Area("Changer")]
public class HomeController : Controller
{
             
}
