magento2 – How to fix validate class not found from basename Magento?

I’ve moved my Magento 2.3.2 website from Shared Hosting where I developed it to a VPS. Everything on the Shared Hosting was working fine on checkout but right now, when a customer login and tries to Checkout this error message appears:

 Validate class not found from basename

I’ve tried and followed this: the Same issue reported.

With what is suggested adding include_path “.” to my php.ini file, the result is, the error message no longer is showing but the delivery methods are not showing.

As it looks it feels like this stops the validation process for the address of the customer. Has anyone found a fix for this?

Edit: I am not using Plesk.
