Your requirements could not be resolved to an installable set of packages. Problem 1 - orchestra/testbench[v8.20.0, ..., 8.x-dev] require laravel/framework ^10.40 -> satisfiable by laravel/framework[v10.40.0, ..., 10.x-dev]. - orchestra/testbench v8.19.0 requires laravel/framework ^10.39 -> satisfiable by laravel/framework[v10.39.0, ..., 10.x-dev]. - orchestra/testbench v8.18.0 requires laravel/framework ^10.37.3 -> satisfiable by laravel/framework[v10.37.3, ..., 10.x-dev]. - orchestra/testbench[v8.15.0, ..., v8.17.0] require laravel/framework ^10.23.1 -> satisfiable by laravel/framework[v10.23.1, ..., 10.x-dev]. - Only one of these can be installed: laravel/framework[v9.52.15, v9.52.16, 9.x-dev, v10.23.1, ..., 10.x-dev], illuminate/container[v11.0.0, ..., 11.x-dev]. laravel/framework replaces illuminate/container and thus cannot coexist with it. - Root composer.json requires illuminate/container ^11.0 -> satisfiable by illuminate/container[v11.0.0, ..., 11.x-dev]. - Root composer.json requires orchestra/testbench ^8.15 -> satisfiable by orchestra/testbench[v8.15.0, ..., 8.x-dev].
