Your lock file does not contain a compatible set of packages. Please run composer update. Problem 1 - maglnet/composer-require-checker is locked to version 4.6.0 and an update of this package was not requested. - maglnet/composer-require-checker 4.6.0 requires php ~8.1.0 || ~8.2.0 -> your php version (8.3.0) does not satisfy that requirement.
