Hikashop Content module format broken

-- HikaShop version -- : 6.1.1
-- Joomla version -- : 6.01
-- PHP version -- : 8.3
-- Browser(s) name and version -- : Chrome,ie,firefox
-- Error-message(debug-mod must be tuned on) -- : None shown

I set up a new preproduction environment and have an issue when attempting to define\setup a new site module

System >> SIte Modules >> Click the Joomla "New+" button >> then select the entry for "Hikashop content module"

the page displays as shown in the attachment.

Other Hikashop modules (And the non hikashop modules that are present do present a validly formatted page.

I have turned error reporting on (maximum) but nothing jumped out. - I have also switched template styles and then reverted back to the default Atum. And of course removed Hikashop install and reinstalled - cleared cache etc

Any suggestions on what to look at in troubleshooting this?

Many thanks
