Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires nextcloud/ocp dev-master -> satisfiable by nextcloud/ocp[dev-master]. - nextcloud/ocp dev-master requires php ~8.1 || ~8.2 || ~8.3 || ~8.4 -> your php version (8.0; overridden via config.platform, actual: 8.2.27) does not satisfy that requirement.
