I have a project using symfony 7 and easyadmin 4.
All features worked fine untill I upgraded to the latest Symfony 7 release where editing CollectionFields by adding new elements started behaving erratically.

When I add a new item in a collectionField in edit mode, it does override the last element instead of adding a new instance in the collection.

Only way to get around the issue is to revert back to version 6.4.7 of Symfony.
