I've just updated my system and obs-studio isn't starting anymore.
of course it's Qt related, i'd like to know how to solve.
on my distro it's not available anymore Qt 5.x

It seem some qt packages are not updated, please post qlist -Iv 'dev-qt/*' output.

ok, i removed in my make.conf the -qt5 flag, recompiled the packages needing update at that point,and then obs started working again

The problem is not qt5 but the fact that you previously had some qt6 packages with version 6.6.1 and 6.6.2 that cannot work.
All installed qt packages of a major version (5,6) must have the same minor version.
