But In actual I have the WorldlineCheckoutForm class same way when I go for Payment method module I get access denied but I am logedin as admin which has all rights. I tried to check support but could not succeed. I am able to access all pages except this particular module.

Answer 1

Try the following things:

1. Delete the module completely and install it on Fresh Drupal installation.
2. In your existing installation, clear the cache by using cli or page (whatever you can access) and then try to access payment page again. (3) Also open that page of your existing installation in Incognito mode so that it cannot get anything from cache

Hope these steps help, otherwise upload it elsewhere and share the link.
