Did you do composer install after cloning this repository?
Then the vendor directory should exist
After that ... check if /vendor/autoload.php exists

Becarefull about the php version. Because current this project using php version 7, if you are using 8. After clone you need to delete composer.lock file and edit the version ^7.3|^8.0 inside the composer.json, then composer install again.
