Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires illuminate/contracts ^10.0 -> satisfiable by illuminate/contracts[v10.0.0, ..., 10.x-dev]. - orchestra/testbench 7.x-dev requires laravel/framework ^9.52.16 -> satisfiable by laravel/framework[v9.52.16, 9.x-dev]. - Only one of these can be installed: laravel/framework[v7.20.0, ..., 7.x-dev, v8.19.0, ..., 8.x-dev, v9.0.0-beta.1, ..., 9.x-dev], illuminate/contracts[v10.0.0, ..., 10.x-dev]. laravel/framework replaces illuminate/contracts and thus cannot coexist with it. - Root composer.json requires orchestra/testbench 7.x-dev -> satisfiable by orchestra/testbench[7.x-dev].
