Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires drush/drush ^12 -> satisfiable by drush/drush[12.0.0, ..., 12.5.3]. - drush/drush[12.0.0, ..., 12.5.3] require symfony/event-dispatcher ^6 -> found symfony/event-dispatcher[v6.0.0, ..., v6.4.13] but these were not loaded, likely because it conflicts with another require.

Not enough arguments (missing: "version").
