Hi there!
Sorry for your experience.
Your person addon issue has been solved. Please check and let me know.
However, I can see you have upgrded to Joomla 5 and PHP 8.3, but the Spectrum template is not compatible with Joomla 5 and PHP 8.3 yet, officially.
Moreover, you have kept Helix Ultimate and Helix3 both framework at the same time in your this site, which is not recommended as these frameworks are different in many areas, thus may result conflicts. So recommendation is keep only one framework and relevant templates based on the single framework, then remove the other framework and it's templates completely, even the system plugin also.
Best Regards
