Start by running `vendor/bin/mftf upgrade:tests` on v4.2.1 and inspect `src/Magento/FunctionalTestingFramework/Upgrade/RemoveUnusedArguments.php` at line 43, following its invocation from `Console/UpgradeTestsCommand.php`. Trace why `ActionGroupArgumentsCheck` cannot be loaded and verify that the upgrade command completes without the fatal error.
