PHP Fatal error on 10LTS + PHP 7.4

[misterboe]

When i make a composer updaten on a 10TLS PHP7.4 install version 2.x is loaded via composer. This leads to

PHP Fatal error: Uncaught ArgumentCountError: Too few arguments to function TYPO3\CMS\Core\Localization\LanguageServiceFactory::__construct(), 0 passed in /typo3/sysext/core/Classes/Utility/GeneralUtility.php on line 3492 and exactly 2 expected in typo3/sysext/core/Classes/Localization/LanguageServiceFactory.php:37

It seems like Version 2 needs PHP >= 8.0. There must be something wrong in the composer.json that i could load 2.x on 7.4
