Your requirements could not be resolved to an installable set of packages.
Problem 1
- Root composer.json requires symfony/var-dumper ^7.1 -> satisfiable by symfony/var-dumper[v7.1.0-BETA1, ..., 7.2.x-dev].
- symfony/var-dumper[v7.1.0-BETA1, ..., 7.2.x-dev] require php >=8.2 -> your php version (8.0.30) does not satisfy that requirement.
