Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires illuminate/contracts 10.* -> satisfiable by illuminate/contracts[v10.0.0, ..., 10.x-dev]. - Root composer.json requires pestphp/pest-plugin-laravel ^3.0 -> satisfiable by pestphp/pest-plugin-laravel[v3.0.0, 3.x-dev]. - pestphp/pest-plugin-laravel[v3.0.0, ..., 3.x-dev] require laravel/framework ^11.22.0 -> satisfiable by laravel/framework[v11.22.0, ..., 11.x-dev]. - Only one of these can be installed: laravel/framework[v11.0.0, ..., 11.x-dev], illuminate/contracts[v10.0.0, ..., 10.x-dev]. laravel/framework replaces illuminate/contracts and thus cannot coexist with it.
