Accepted AnswerApologies for the inconvenience. The latest version of Helix Ultimate currently has a known issue with Joomla 4.
As an immediate workaround, you can resolve this by replacing the plugins/system/helixultimate/helixultimate.php file with the attached fixed version.
We appreciate your patience and understanding while we work to fully address this compatibility issue.
