Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires symfony/options-resolver ~4.0.15 || ~4.1.9 || ^4.2.1 || ^5.0 || ^6.0 || ^7.0 || ^8.0, found symfony/options-resolver[v4.0.15, ..., v4.4.44, v5.0.0, ..., v5.4.45, v6.0.0, ..., v6.4.25, v7.0.0, ..., v7.3.3] but these were not loaded, likely because it conflicts with another require.
