Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires drupal/config_sync_without_site_uuid ^1.0@beta -> satisfiable by drupal/config_sync_without_site_uuid[1.0.0-beta1]. - drupal/config_sync_without_site_uuid 1.0.0-beta1 requires drupal/core ^9 || ^10 -> found drupal/core[9.0.0-alpha1, ..., 9.5.x-dev, 10.0.0-alpha1, ..., 10.2.x-dev] but it conflicts with your root composer.json require (11.x-dev). Problem 2 - acquia/blt[dev-main, 13.x-dev] require drupal/core ^10.0.0 -> found drupal/core[10.0.0-alpha1, ..., 10.2.x-dev] but it conflicts with your root composer.json require (11.x-dev). - acquia/blt 13.x-dev is an alias of acquia/blt dev-main and thus requires it to be installed too. - Root composer.json requires acquia/blt * -> satisfiable by acquia/blt[dev-main, 13.x-dev (alias of dev-main)].
