Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires webmozart/assert ^2.0 -> satisfiable by webmozart/assert[2.0.0, 2.1.0, 2.1.1, 2.1.2]. - webmozart/assert[2.0.0, ..., 2.1.2] require php ^8.2 -> your php version (8.1.33) does not satisfy that requirement. Problem 2 - Root composer.json requires laminas/laminas-cache ^4.1.0 -> satisfiable by laminas/laminas-cache[4.1.0, 4.2.0]. - laminas/laminas-cache 4.1.0 requires webmozart/assert ^1.11 -> found webmozart/assert[1.11.0, 1.12.0, 1.12.1] but it conflicts with your root composer.json require (^2.0). - laminas/laminas-cache 4.2.0 requires php ~8.2.0 || ~8.3.0 || ~8.4.0 || ~8.5.0 -> your php version (8.1.33) does not satisfy that requirement.
