The job was canceled because "_7_4" failed.

Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires symfony/var-dumper ^7.0 -> satisfiable by symfony/var-dumper[v7.0.0, ..., v7.2.0]. - symfony/var-dumper[v7.0.0, ..., v7.2.0] require php >=8.2 -> your php version (8.0.30) does not satisfy that requirement.
