Laravel 10: Class "League\Flysystem\AwsS3V3\PortableVisibilityConverter" not found

Question

in my prod environment I'm having this error while locally everything works perfectly.

I don't know what's wrong with it. I suspect there are some problem related to composer but it's not clear to me how to fix this.

As suggested in Laravel I have installed: composer require league/flysystem-aws-s3-v3 "^3.0" --with-all-dependencies

I've also try composer dump-autoload and as last chance I've fully removed the vendor folder and composer install but the problem persist.

This is the composer output:

Just running
