The job was canceled because "_5_5___7_2" failed.

Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires symfony/var-exporter ^7.0.4 -> satisfiable by symfony/var-exporter[v7.0.4]. - symfony/var-exporter v7.0.4 requires php >=8.2 -> your php version (7.4.33) does not satisfy that requirement.
