How do I solve ERR_TOO_MANY_REDIRECTS error?

I applied the solution proposed on to many redirects login security.yml but I’m still getting the same error.

security.yaml

security:
    encoders:
        AppEntityUser:
            algorithm: auto

providers
    providers:
        app_user_provider:
            entity:
                class: AppEntityUser
                property: email
                
    firewalls:
        dev:
            pattern: ^/(_(profiler|wdt)|css|images|js)/
            security: false
        # Added this to the code in order to solve ERR_TOO_MANY_REDIRECTS issue 
        login_firewall:
            pattern: ^/login$
            anonymous: ~

        main:
            anonymous: true
            lazy: true
            provider: app_user_provider
            guard:
                authenticators:
                    - AppSecurityLoginFormAuthenticator
            logout:
                path: app_logout
                
            remember_me:
                secret:   '%kernel.secret%'
                lifetime: 604800 # 1 week in seconds
                path:     /

    access_control:
        - { path: ^/usuarios, roles: ROLE_ADMIN }
        - { path: ^/usuario, roles: ROLE_ADMIN }
        - { path: ^/incidencias, roles: ROLE_ADMIN }
        - { path: ^/incidencia, roles: ROLE_ADMIN }
        - { path: ^/modulos, roles: ROLE_ADMIN }
        - { path: ^/modulo, roles: ROLE_ADMIN }
        - { path: ^/categorias, roles: ROLE_ADMIN }
        - { path: ^/categoria, roles: ROLE_ADMIN }
        - { path: ^/generos, roles: ROLE_ADMIN }
        - { path: ^/genero, roles: ROLE_ADMIN }
        - { path: ^/estadisticas, roles: ROLE_ADMIN }
        # - { path: ^/profile, roles: ROLE_USER }

I also removed a redirect from DefaultController.php in order to avoid extra redirects. However, I need to keep the redirect for the case in which the user is not found.

DefaultController.php

use SymfonyBundleFrameworkBundleControllerAbstractController;
use SymfonyComponentHttpFoundationRequest;
use SymfonyComponentHttpFoundationRedirectResponse;

class DefaultController extends AbstractController
{
    public function index()
    {
        //$request = Request::createFromGlobals();
        
        //redirect to workinprogress again if the url target is not from workinprogress webpage
        //if (!$request->query->get('from')) {
        //    $redirect = new RedirectResponse('/');
        //    $redirect->setTargetUrl('https://estudio-workinprogress.com/area-privada/');
        //    return $redirect;
        //}

        if($this->getUser() == null) {
            return $this->redirectToRoute('app_login');
        }
            
        return $this->redirectToRoute('get_escenas');
    }
}
