Hello,
I've got the same problem , when trying to install PS 1.8.1.1 on my testing Centos 7.9 (with Apache/2.4.6 (CentOS) PHP/7.4.33 and MySQL version: 5.5.68-MariaDB) . And just like severall of my predecessors said the error messages started with module-installing sections and it looks just like :

(of course I've changed the last octets of IP addresses )
From the browser point of view - this looks like :
Do You PS Guys & Developers - know - WHAT is the real REASON OF THIS DISTURBING PROBLEM ??
And HOW TO better TROUBLESHOOT IT ???
(No, that's obviously not the problem of configuration php - I've tested severall configurations esp. with very enlarged time_liimits ... and so on - and nothing makes the difference at all !)
Additionally - the problem DOES NOT affect the PS 1.7.xx versions - but only 1.8 releases !!
