When the User Groups option is disabled, the Admin Panel crashes

[petira]

When the User Groups option is disabled, the Admin Panel crashes.

The solution is to add the - 'blueprints://flex-objects/user-groups.yaml' record to the directories area in the flex-object.yaml file.

Error thrown with message "Call to a member function select() on null".
