Your requirements could not be resolved to an installable set of packages. Problem 1 - symfony/framework-bundle[v6.1.0, ..., v6.3.9] require symfony/config ^6.1 -> found symfony/config[v6.1.0, ..., v6.4.0] but these were not loaded, likely because it conflicts with another require. - symfony/framework-bundle[v6.4.0, ..., v6.4.1] require symfony/config ^6.1|^7.0 -> found symfony/config[v6.1.0, ..., v6.4.0, v7.0.0] but these were not loaded, likely because it conflicts with another require. - symfony/framework-bundle[v7.0.0, ..., v7.0.1] require php >=8.2 -> your php version (8.1.26) does not satisfy that requirement. - Root composer.json requires symfony/framework-bundle ^6.1|^7.0 -> satisfiable by symfony/framework-bundle[v6.1.0, ..., v6.4.1, v7.0.0, v7.0.1]. Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
