Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires gponty/symfony-monday-api-bundle ^1.0 -> satisfiable by gponty/symfony-monday-api-bundle[1.0, ..., 1.04]. - gponty/symfony-monday-api-bundle[1.0, ..., 1.04] require php >=8.1 -> your php version (7.4.33) does not satisfy that requirement.
