Your requirements could not be resolved to an installable set of packages. Problem 1 - setono/post-nord-bundle[v1.0.0, ..., v1.1.0] require php ^7.2 -> your php version (8.1.29) does not satisfy that requirement. - setono/post-nord-bundle v1.2.0 requires symfony/config ^4.4 || ^5.0 -> found symfony/config[v4.4.0, ..., v4.4.44, v5.0.0, ..., v5.4.40] but these were not loaded, likely because it conflicts with another require. - Root composer.json requires setono/post-nord-bundle ^1.0 -> satisfiable by setono/post-nord-bundle[v1.0.0, ..., v1.2.0].
