I can confirm the same btu can add more details about the env and an alternative approach

My environment:

PHP 8.3
Symfony 6.4.15

My steps to get it working

  • Install using the documented approach composer require composer-unused/composer-unused-plugin
  • Confirm the question: Do you trust "composer-unused/composer-unused-plugin" to execute code and wish to enable it now? (writes "allow-plugins" to composer.json)
  • The install fails with the error Class "__ComposerUnused__\Symfony\Component\DependencyInjection\ContainerBuilder" not found
  • Running php ./vendor/composer-unused/composer-unused-plugin/composer-unused.phar works and I get an expected output.
