Symfony version(s) affected

6.2.2

Description

When using the version 6.2.2 of symfony/expression-language the #[Assert\Expression] validation constraint is broken and validation always fails. The issue does appear only in production environment.

How to reproduce

• Setup reproducer app:

git clone https://github.com/jbroutier/sf-expression-language-issue
cd sf-expression-language-issue
composer install
php -S 0.0.0.0:8080 -t public

• Open browser and navigate to http://127.0.0.1:8080.
• Fill the form and submit it, validation passes.
• Fill the form again and submit it, validation fails. Removing the cache fixes the issue for another round.

Possible Solution

Likely caused by #48559. As a temporary workaround, reverting symfony/expression-language to version 6.2.0 fixes the issue.
