Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires symfony/filesystem 8.0.0 (exact version match: 8.0.0 or 8.0.0.0), found symfony/filesystem[v8.0.0] but the package is fixed to v6.2.5 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command. Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
