Our website dev2.unitedsocceracademy can't load the page layouts menu on the administrator or site side. We are on PHP 8.1, Joomla 4.4, and SP page Builder version 5.1.6.
Currently, when I try to access page layouts I get this screen: a black screen that stays loading,
If I wait long enough I get a 504 error.
This is the website in question https://dev2.unitedsocceracademy.com/
