Problem/Motivation
Webform can't be accessed, when module is enabled. The following error is thrown:
TypeError: Drupal\Core\Access\AccessResult::orIf(): Argument #1 ($other) must be of type Drupal\Core\Access\AccessResultInterface, null given, called in /var/www/html/web/modules/contrib/webform/src/Plugin/WebformElementBase.php on line 918 in Drupal\Core\Access\AccessResult->orIf() (line 282 of /var/www/html/web/core/lib/Drupal/Core/Access/AccessResult.php)
