Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires symfony/ux-lazy-image ^2.17 -> satisfiable by symfony/ux-lazy-image[v2.17.0, 2.x-dev]. - symfony/ux-lazy-image[v2.17.0, ..., 2.x-dev] require php >=8.1 -> your php version (7.4.33) does not satisfy that requirement.
