Aki WordPress Theme - Arrowpress / PHP Issue / Conflict

Hi. Our website www.edukidz.co.za was working perfectly until PHP 8.1. Now the site has a critical error. This error is related to ArrowPress itself. When deactivated, we can get onto the back end but cannot do much. When ArrowPress is activated, the site breaks immediately. Has anyone else had the same experience? How can we resolve this issue. Please help!
