Your requirements could not be resolved to an installable set of packages. Problem 1 - illuminate/notifications v9.0.0 requires illuminate/support ^9.0 -> found illuminate/support[v9.0.0-beta.1, ..., 9.x-dev] but it conflicts with your root composer.json require (^10.0|^11.0). - Only one of these can be installed: laravel/framework[v11.0.0, ..., 11.x-dev], illuminate/notifications[v9.0.0, v10.0.0, ..., 10.x-dev]. laravel/framework replaces illuminate/notifications and thus cannot coexist with it. - Root composer.json requires illuminate/notifications 9.0 || ^10.0 -> satisfiable by illuminate/notifications[v9.0.0, v10.0.0, ..., 10.x-dev]. - Root composer.json requires laravel/framework 11.* -> satisfiable by laravel/framework[v11.0.0, ..., 11.x-dev].
