    I don’t know how to correct fix it, but I just reverted 

    symfony/twig-bridge to v4.2.8
twig/twig to v2.10.0

    And all ok for me now. I hope it help you.

    I set in composer.json

    "symfony/twig-bridge": "4.2.8",
"twig/twig": "2.10"

    and updated composer.

    This error was caused by an issue at @SonataAdmin/CRUD/base_edit_form.html.twig. It is fixed at v3.49.0. See the related PR.
