That's a bug that has been fixed within the last hours. Can you try to run your command again? — Nico Haase

Seems many people have the same issue

Downgrade temporarilyy and manually to symfony/translate 5.3.7 or lower

If you have symphony in composer.json file, downgrading the version would work. If not just add "Symfony/translation": "4.3.8"

"require": {
     ...
     "symfony/translation": "4.3.8",
    }

and then composer update

The version may be different so keep that in mind.
