Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires babdev/pagerfanta-bundle ^4.0 -> satisfiable by babdev/pagerfanta-bundle[v4.0.0, ..., 4.x-dev]. - babdev/pagerfanta-bundle[v4.0.0, ..., 4.x-dev] require symfony/config ^5.4 || ^6.2 -> found symfony/config[v5.4.0-BETA1, ..., 5.4.x-dev, v6.2.0-BETA1, ..., 6.4.x-dev] but these were not loaded, likely because it conflicts with another require. Problem 2 - Root composer.json requires nelmio/security-bundle ^3.0 -> satisfiable by nelmio/security-bundle[v3.0.0-alpha.1, v3.0.0, 3.x-dev]. - nelmio/security-bundle[v3.0.0-alpha.1, ..., 3.x-dev] require symfony/framework-bundle ^4.4 || ^5.4 || ^6.0 -> found symfony/framework-bundle[v4.4.0-BETA1, ..., 4.4.x-dev, v5.4.0-BETA1, ..., 5.4.x-dev, v6.0.0-BETA1, ..., 6.4.x-dev] but these were not loaded, likely because it conflicts with another require.
