Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires illuminate/collections ^11 -> satisfiable by illuminate/collections[v11.0.0, ..., v11.23.5]. - illuminate/collections[v11.0.0, ..., v11.23.5] require php ^8.2 -> your php version (8.1.2) does not satisfy that requirement.
