Your requirements could not be resolved to an installable set of packages. Problem 1 - symfony/config[v6.2.0, ..., v6.4.0] require php >=8.1 -> your php version (8.0.30) does not satisfy that requirement. - Root composer.json requires symfony/config ^4.3 || ^5.4 || ^6.2 -> satisfiable by symfony/config[v6.2.0, ..., v6.4.0].
