Honestly, I think it is a Joomla 4 issue. All these sites are on the same server with cPanel.
When trying to update via Watchful I get errors, I am able to update J3 sites in the admin successfully.
I do notice that the file path is like this though in the extension update:
shaper_helixultimate
Site Template 2.0.10 2.0.11 N/A Update https://www.joomshaper.com/updates/shaper-helixultimate.xml
System - Helix Ultimate Framework
Site Plugin 2.0.10 2.0.11 system Update http://www.joomshaper.com/updates/plg-system-helixultimate.xml
Here is the admin after installing SP Page Builder 4.0.3

I am also using the Fixter template. Is this PHP 8 compatible?
When I restore back to the 3.88 version all is working as expected.
