Thanks Rajab for your patch
Laurent222 → created an issue.
After checking all the permissions one by one I actually managed to find out what the problem was, and it was indeed a permission problem. Thanks for your answer. Have a good day.
I have a menu with a link that displays a form that allows me to create a user (a person) of the site and the link points to the url: admin/people/create. And I want to create a second form to create users (company) this time that do not have the same fields as the user. And for that I used the input mode of Drupal 9. And with this input mode I managed to create my two different forms that work correctly when I am logged in as admin. The url of the second form : admin/people/create/company. But when I disconnect from the admin user and reconnect with another user the admin/people/create url works correctly but the one with admin/people/create/company does not work anymore. I specify I only used the graphical interface.
