Fatal error on uninstallation / SOLUTION

solution : edit file cookie-script.php and replace : line 418 to 449 .

replace that :

public function cookie_script_deactivation() {
        wp_dequeue_script("cookie_script");
    }

    // Clean up DB after uninstalling plugin
    public function cookie_script_uninstall() {

        if (!current_user_can("activate_plugins")) {
            return null;
        }

        delete_option("cookie_script_item_id");
        delete_option("cookie_script_item_src");
        delete_option("cookie_script_item_connection_type");
        delete_option("cookie_script_location");
        delete_option("cookie_script_location_in_element");

        wp_dequeue_script("cookie_script");
        wp_deregister_script("cookie_script");

    }

}

new CookieScript();

// Make sure there is no cookie script in document while plugin is deactivated
register_deactivation_hook( __FILE__, array("CookieScript", "cookie_script_deactivation") );

// Clean up DB after uninstalling plugin
register_uninstall_hook( __FILE__, array("CookieScript", "cookie_script_uninstall") );

………………………………………………………………………

per that

    public static function cookie_script_deactivation() {
    wp_dequeue_script("cookie_script");
}

// Clean up DB after uninstalling plugin
public static function cookie_script_uninstall() {

    if (!current_user_can("activate_plugins")) {
        return null;
    }

    delete_option("cookie_script_item_id");
    delete_option("cookie_script_item_src");
    delete_option("cookie_script_item_connection_type");
    delete_option("cookie_script_location");
    delete_option("cookie_script_location_in_element");

    wp_dequeue_script("cookie_script");
    wp_deregister_script("cookie_script");

}

}

$new_instance = new CookieScript();

// Make sure there is no cookie script in document while plugin is deactivated
register_deactivation_hook( __FILE__, array($new_instance, "cookie_script_deactivation") );

// Clean up DB after uninstalling plugin
register_uninstall_hook( __FILE__, array($new_instance, "cookie_script_uninstall") );

and if you got a lot of php warning message like this : [29-Sep-2023 18:58:51 UTC] PHP Warning: Undefined variable $conn in /home/intellis/xxxxxxx.com/wp-content/plugins/cookie-script-com/cookie-script.php on line 395

edit file cookie-script.php line 378 to 394

and replace this

public function cookie_script_generate_url() {


    $url = null;

    switch ($this->item_connection_type) {
        case 1:
            $conn = "https://cdn.";
            break;
        case 2:
            $conn = "https://eu.";
            break;
        case 3:
            $conn = "https://ca.";
            break;
        case 4:
            $conn = "https://ca-eu.";
            break;
    }

whit this

   public function cookie_script_generate_url() {

    $url = null;
    $conn = "";

    switch ($this->item_connection_type) {
        case 1:
            $conn = "https://cdn.";
            break;
        case 2:
            $conn = "https://eu.";
            break;
        case 3:
            $conn = "https://ca.";
            break;
        case 4:
            $conn = "https://ca-eu.";
            break;
        default:
            $conn = "";
            break;
    }

Thank you!! Thanks to the first code, I managed to deactivate the plugin, and thanks to the second one, I was able to delete it.
