Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
You can also try re-running composer require with an explicit version constraint, e.g. "composer require symfony/webapp-pack:*" to figure out if any version is installable, or "composer require symfony/webapp-pack:^2.1" if you know which you need.
 
Installation failed, reverting ./composer.json and ./composer.lock to their original content.

Je précise que je suis sur PHP 8.3.0

J'avais un conflit avec une ancienne version de php (7.*), j'ai donc désinstallé php (toutes les versions) puis réinstallé php 8.2 et tout fonctionne correctement depuis.
