Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires symfony/property-access ^6.0 || ^7.0 -> satisfiable by symfony/property-access[v6.0.0, ..., v6.0.19]. - symfony/property-access[v6.0.0, ..., v6.0.19] require symfony/property-info ^5.4|^6.0 -> found symfony/property-info[v5.4.0, ..., v5.4.35, v6.0.0, ..., v6.4.3] but it conflicts with your root composer.json require (^7.0). Problem 2 - Root composer.json requires symfony/property-info ^7.0 -> satisfiable by symfony/property-info[v7.0.0, v7.0.3]. - symfony/property-info[v7.0.0, ..., v7.0.3] require symfony/string ^6.4|^7.0 -> found symfony/string[v6.4.0, v6.4.2, v6.4.3, v6.4.4, v7.0.0, v7.0.2, v7.0.3, v7.0.4] but these were not loaded, likely because it conflicts with another require.
