Description
I noticed that after updating from 4.4.1 to 4.4.2 couple of my tests are failing with following stack trace
Failed asserting that exception of type "RuntimeException" matches expected exception "Symfony\Component\Validator\Exception\ValidatorException". Message was: "A type is missing in a collection expression" at

That test is trying to validate one of my DTO's and after a little bit testing I tracked that error to following;
/**
* @var UserGroupEntity[]|array<int, UserGroupEntity>
*
* @AppAssert\EntityReferenceExists(entityClass=UserGroupEntity::class)
*/
protected array $userGroups = [];
If I remove that @var UserGroupEntity[]|array<int, UserGroupEntity> line on my DTO, tests doesn't fail and if I run exactly same test within 4.4.1 there isn't that error.
So it seems like some bug fix has caused this side effect in certain use cases.
