Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires composer/pcre ^2.3 || ^3.3 -> satisfiable by composer/pcre[3.3.2]. - composer/pcre 3.3.2 requires php ^7.4 || ^8.0 -> your php version (7.2.5; overridden via config.platform, actual: 8.4.14) does not satisfy that requirement. Problem 2 - composer/xdebug-handler is locked to version 3.0.5 and an update of this package was not requested. - composer/pcre 3.3.2 requires php ^7.4 || ^8.0 -> your php version (7.2.5; overridden via config.platform, actual: 8.4.14) does not satisfy that requirement. - composer/xdebug-handler 3.0.5 requires composer/pcre ^1 || ^2 || ^3 -> satisfiable by composer/pcre[3.3.2].
