Thought its not listed as a dependancy, a query of the system for icu with pacman -F libicuuc.so shows;

core/icu 75.1-1 [installed]
    usr/lib/libicuuc.so
extra/intel-oneapi-basekit 2024.0.0.49564-3
    opt/intel/oneapi/advisor/2024.0/fga/fga/libicuuc.so
multilib/lib32-icu 75.1-1 [installed]
    usr/lib32/libicuuc.so

clearly the installed version is 75 but the application is asking for version 74.

This might also be the case on other updated distros.

On arch or other arch based distro the solution is to install AUR package icu74 alongside the main repo package of icu as described here

Might be worth to update the application to use the newer icu library and to also mention it as a dependancy.
