Add to your theme hook to always have user roles.

User Role

  public function base_render_before($sender) {
        if(!val('UserRoles', $sender->Data)) {
            $user = val('User', Gdn::controller());
            if (!$user && Gdn::session()->isValid()) {
                $user = Gdn::session()->User;
            }
            $userRoles = [];
            if ($user) {
                $userID = val('UserID', $user);
                $userRolesData = Gdn::userModel()->getRoles($userID);
                if ($userRolesData->numRows() > 0) {
                    $userRoles = array_column($userRolesData->resultArray(), 'Name');
                }
            }
            $sender->setData('UserRoles', $userRoles);
        }
    }
