Steps to reproduce the issue

Enable PHP OpCache on the server

Install an extension that uses the new service provider architecture

Expected result

As soon as the extension is installed it works normally

Actual result

Classes are not auto loaded and found by the PHP process.
For example the main \Extension\NameComponent.php file and related class Vendorname\Component\Componentname\Administrator\Extension\ComponentnameComponent that is loaded in the services.php file is not found and an error occurs.

After a few seconds the OpCache refreshes and reloading the page the component starts to work normally.

System information (as much as possible)

Linux server
PHP 7.4
OpCache enabled

Additional comments

The problem does not happen when PHP OpCache is disabled
Probably this should be a release blocker.
