Type Error in Laravel 8 app when package barryvdh/laravel-translation-manager is installed

For last 3-4 weeks I receive this error in my Laravel 8 app, which breaks down my app. After uninstalling the package the problem disappears.

Please advice.

When using the Laravel app:

TypeError
Argument 2 passed to Symfony\Component\Translation\Translator::addResource() must be an instance of Symfony\Component\Translation\mixed, array given, called in D:\www\MyBooks\vendor\nesbot\carbon\src\Carbon\AbstractTranslator.php on line 165

when updating the app and dependencies:

TypeError
