Your requirements could not be resolved to an installable set of packages. Problem 1 - symfony/amqp-messenger[v6.0.0, ..., v6.4.8] require ext-amqp * -> it is missing from your system. Install or enable PHP's amqp extension. - symfony/amqp-messenger[v7.0.0, ..., v7.1.1] require php >=8.2 -> your php version (8.1.27) does not satisfy that requirement. - Root composer.json requires symfony/amqp-messenger ^6.0 || ^7.0 -> satisfiable by symfony/amqp-messenger[v6.0.0, ..., v6.4.8, v7.0.0, ..., v7.1.1].

Alternatively, you can run Composer with `--ignore-platform-req=ext-amqp` to temporarily ignore these required extensions.
