Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires doctrine/doctrine-fixtures-bundle ^3.5.1 || ^4.0 -> satisfiable by doctrine/doctrine-fixtures-bundle[3.5.1, ..., 3.7.2, 4.0.0, ..., 4.3.0]. - doctrine/doctrine-fixtures-bundle[3.5.1, ..., 3.7.0] require symfony/config ^5.4|^6.0|^7.0 -> found symfony/config[v5.4.0, ..., v5.4.46, v6.0.0, ..., v6.4.28, v7.0.0, ..., v7.4.0] but these were not loaded, likely because it conflicts with another require. - doctrine/doctrine-fixtures-bundle[3.7.1, ..., 3.7.2, 4.0.0] require symfony/config ^5.4 || ^6.0 || ^7.0 -> found symfony/config[v5.4.0, ..., v5.4.46, v6.0.0, ..., v6.4.28, v7.0.0, ..., v7.4.0] but these were not loaded, likely because it conflicts with another require. - doctrine/doctrine-fixtures-bundle[4.1.0, ..., 4.3.0] require symfony/config ^6.4 || ^7.0 -> found symfony/config[v6.4.0, ..., v6.4.28, v7.0.0, ..., v7.4.0] but these were not loaded, likely because it conflicts with another require. Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
