Your requirements could not be resolved to an installable set of packages. Problem 1 - symfony/form[v6.0.0, ..., v6.0.19] require php >=8.0.2 -> your php version (7.4.33) does not satisfy that requirement. - symfony/form[v6.1.0, ..., v6.4.0] require php >=8.1 -> your php version (7.4.33) does not satisfy that requirement. - Root composer.json requires symfony/form ^3.4|^4.0|^5.0|^6.0|^7.0 -> satisfiable by symfony/form[v6.0.0, ..., v6.4.0].
