Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires drupal/core 10.4.x-dev -> satisfiable by drupal/core[10.4.x-dev]. - drupal/core 10.4.x-dev requires symfony/http-foundation ^6.4 -> found symfony/http-foundation[v6.4.0-BETA1, ..., 6.4.x-dev] but these were not loaded, because they are affected by security advisories. To ignore the advisories, add ("PKSA-365x-2zjk-pt47") to the audit "ignore" config. To turn the feature off entirely, you can set "block-insecure" to false in your "audit" config. Problem 2 - Root composer.json requires drupal/drush_language * -> satisfiable by drupal/drush_language[dev-1.x, 1.0.0-rc1, ..., 1.x-dev]. - drupal/core 10.4.x-dev requires symfony/http-foundation ^6.4 -> found symfony/http-foundation[v6.4.0-BETA1, ..., 6.4.x-dev] but these were not loaded, because they are affected by security advisories. To ignore the advisories, add ("PKSA-365x-2zjk-pt47") to the audit "ignore" config. To turn the feature off entirely, you can set "block-insecure" to false in your "audit" config. - drupal/drush_language[1.0.0-rc1, ..., 1.0.0-rc2] require drupal/core ^8 -> satisfiable by drupal/core[8.0.0-beta6, ..., 8.9.x-dev] from composer repo (https://repo.packagist.org) but drupal/core[10.4.x-dev] from path repo (core) has higher repository priority. The packages from the higher priority repository do not match your constraint and are therefore not installable. That repository is canonical so the lower priority repo's packages are not installable. See https://getcomposer.org/repoprio for details and assistance. - drupal/drush_language[1.0.0-rc3, ..., 1.0.0-rc4] require drupal/core ^8.7.7 || ^9 -> satisfiable by drupal/core[8.7.7, ..., 8.9.x-dev, 9.0.0-alpha1, ..., 9.5.x-dev] from composer repo (https://repo.packagist.org) but drupal/core[10.4.x-dev] from path repo (core) has higher repository priority. The packages from the higher priority repository do not match your constraint and are therefore not installable. That repository is canonical so the lower priority repo's packages are not installable.
