Your requirements could not be resolved to an installable set of packages. Problem 1 - Only one of these can be installed: laravel/framework[v10.0.0, ..., 10.x-dev], illuminate/contracts[v11.8.0, ..., 11.x-dev]. laravel/framework replaces illuminate/contracts and thus cannot coexist with it. - Root composer.json requires illuminate/contracts ^11.8 -> satisfiable by illuminate/contracts[v11.8.0, ..., 11.x-dev]. - Root composer.json requires laravel/framework 10.* -> satisfiable by laravel/framework[v10.0.0, ..., 10.x-dev].
