Invalid key supplied at vendor/league/oauth2-server/src/CryptKey.php in Laravel app

Question

Stack: Laravel 11 - Ubuntu 24.04 - PHP 8.3 - Composer 2.7.1

I pulled a Laravel app from Gitlab and when running composer install I got this error:

Invalid key supplied at vendor/league/oauth2-server/src/CryptKey.php

No matter which php artisan command I run, the same error shows up again and again.

BTW, there is no keys under storage directory.

I've read several posts about similar issues, but haven't found yet a solution.

Am I maybe missing something?
