Symfony version(s) affected

7.1 RC1

Description

I just tested 7.1 RC1 on my biggest app and I noticed this error:

ReflectionException:
Property Proxies\__CG__\CA\Core\UserBundle\Entity\User::$email does not exist

  at vendor/symfony/doctrine-bridge/Validator/Constraints/UniqueEntityValidator.php:298

How to reproduce

Unfortunately I cannot reproduce this issue yet on a smaller app like symfony-demo. Still looking into it 😕
See #57075 (comment)

Possible Solution

use PropertyAccessor to get the value here?

Additional Context

Downgrading DoctrineBridge and PropertyInfo to 7.0.7 solves the issue for me.
