Redirecting wp-login.php makes log in button keep redirect to the same custom lo

I have copied wp-login.php code in a template file in my theme Created a new page and assigned the template /login

Added the following code in function.php

// Hook the appropriate WordPress action
add_action('init', 'prevent_wp_login');

function prevent_wp_login()
{
    // WP tracks the current page - global the variable to access it
    global $pagenow;
    // Check if a $_GET['action'] is set, and if so, load it into $action variable
    $action = (isset($_GET['action'])) ? $_GET['action'] : '';
    // Check if we're on the login page, and ensure the action is not 'logout'
    if ($pagenow == 'wp-login.php' && (!$action || ($action && !in_array($action, array('logout', 'lostpassword', 'rp', 'resetpass'))))) {
        // Load the home page url
        $page = '/login';
        // Redirect to the home page
        wp_redirect($page);
        // Stop execution to prevent the page loading for any reason
        exit();
    }
}

the page keeps directing me to the login after pressing the login button
