Issue: Sentry trace Serializer issue
sentry/sentry  sdk 2.4.1

Hi guys,

We create a magento sentry integration. It works well, except in this scenario. 

It requires Magento 2 knowledge

In sentry I see issue with such a name
```Cannot declare class Vendor\Customer\Plugin\Api\CustomerRepositoryPlugin, because the name is already in use```

Inside issue in the message there is a actual exception message. No real Exception trace, just trace about class redeclare.

AbstractSerializer.php somehow recreates plugin class
