Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires laravel/sanctum ^4.0 -> satisfiable by laravel/sanctum[v4.0.0, ..., 4.x-dev]. - laravel/sanctum[v4.0.0, ..., 4.x-dev] require php ^8.2 -> your php version (8.1.30) does not satisfy that requirement.
