Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires maglnet/composer-require-checker ^4.15 -> satisfiable by maglnet/composer-require-checker[4.15.0]. - maglnet/composer-require-checker 4.15.0 requires php ~8.2.0 || ~8.3.0 || ~8.4.0 -> your php version (8.1.31) does not satisfy that requirement.
