This Page isn't working Localhost redirected too many times MVC - asp.net-mvc

Question

Program.cs File with Cookie authentication:
builder.Services.AddAuthentication("CookieAuthentication").AddCookie("CookieAuthentication", options =>
{
options.LoginPath = "/<Login/LoginView";
options.AccessDeniedPath = "/Login/AccessDenied";
});
// Configure the HTTP request pipeline.
app.UseHttpsRedirection();
app.UseStaticFiles();
app.UseRouting();
app.UseAuthentication();
app.UseAuthorization();
app.MapControllerRoute(
name: "default",
pattern: "{controller=Login}/{action=Signup}/{id?}");
app.Run();
Login Controller:
[HttpPost]
[ValidateAntiForgeryToken]
public IActionResult LoginView(string username, string password)
{
if (!ModelState.IsValid)
{
//Error code here
}
if (!UserExists(username, password))//Check if user exists in Database
{
//Error code here
}
TempData["Username"] = username;
return RedirectToAction("Index", "Home");
//I used breakpoint here and this code runs but doesn't work properly.
}
I have also used the [Authorize] attribute on Home Controller to prevent users from accessing it without login.Login/LoginView is the Login rage Path.

For your current scenario,be sure add the [AllowAnonymous] on your Index action in the HomeController. And your LoginPath is /Home/Index, it is no need to be authorized.
[Authorize]
public class HomeController : Controller
{
[AllowAnonymous]
public async Task<IActionResult> Index()
{
//do your stuff...
return View();
}
//....
}
Update:
Cookie authentication to login
Program.cs:
builder.Services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme).AddCookie(options =>
{
options.LoginPath = "/Login/LoginView";
options.AccessDeniedPath = "/Login/AccessDenied";
});
var app = builder. Build();
app.UseHttpsRedirection();
app.UseStaticFiles();
app.UseAuthentication(); //be sure add authentication and authorization middleware.....
app.UseAuthorization();
//...
How to sigh in the user:
[HttpPost]
[ValidateAntiForgeryToken]
public async Task<IActionResult> LoginView(string username, string password)
{
if (!ModelState.IsValid)
{
//Error code here
}
if (!UserExists(username, password))//Check if user exists in Database
{
//Error code here
}
var claims = new List<Claim>
{
new Claim(ClaimTypes.NameIdentifier,username) //add the claims you want...
};
//authProperties you can choose any option you want, below is a sample...
var authProperties = new AuthenticationProperties
{
//IssuedUtc = DateTimeOffset.UtcNow,
//ExpiresUtc = DateTimeOffset.UtcNow.AddHours(1),
//IsPersistent = false
};
var claimsIdentity = new ClaimsIdentity(claims, CookieAuthenticationDefaults.AuthenticationScheme);
await HttpContext.SignInAsync(CookieAuthenticationDefaults.AuthenticationScheme, new ClaimsPrincipal(claimsIdentity), authProperties);
TempData["Username"] = username;
return RedirectToAction("Index", "Home");
}
