500 error on edit page

Hello,

I get an 500 error page when I try to bulk modify nodes via VBO.
Others actions work but "Modify fields value" lead to 500.

The only info about this error tell about twig, but delete files doesn't fix the issue.
Message Notice : Object of class Drupal\Core\Render\Markup could not be converted to int dans __TwigTemplate_171e3b28f12248dd0fe07f73025ba7f5->doDisplay() (/home/xx/www/pfdev/multid9/recommended-project/web/sites/d9dev-pf/files/php/twig/63c967fb41a57___string_template__d01551_VTfBsNPSn-kAwnT3fdBYZ5XCd/YmZRf7ih8TyywTI4DPvnq1zQKU-Fo9AY-CzdHmUyv5Q.php ligne 39)

If you are aware of it or have an idea about how to know more about this.

Thanks
