Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires phpunit/phpunit ^11.5.3 -> satisfiable by phpunit/phpunit[11.5.3, 11.5.x-dev]. - phpunit/phpunit[11.5.3, ..., 11.5.x-dev] require php >=8.2 -> your php version (8.1.31) does not satisfy that requirement. Problem 2 - Root composer.json requires orchestra/testbench ^v7.47.0 || ^8.13.0 || ^9.0.9 -> satisfiable by orchestra/testbench[v7.47.0, ..., 7.x-dev]. - orchestra/testbench[v7.47.0, ..., 7.x-dev] require phpunit/phpunit ^9.5.10 -> found phpunit/phpunit[9.5.10, ..., 9.6.x-dev] but it conflicts with your root composer.json require (^11.5.3).
