Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires liip/test-fixtures-bundle ^2.7.2 -> satisfiable by liip/test-fixtures-bundle[2.7.2]. - liip/test-fixtures-bundle 2.7.2 requires symfony/event-dispatcher ^5.4 || ^6.3 || ^7.0 -> found symfony/event-dispatcher[v5.4.0, ..., v5.4.35, v6.3.0, ..., v6.4.3, v7.0.0, v7.0.2, v7.0.3] but these were not loaded, likely because it conflicts with another require.

Process completed with exit code 2.
