In files /etc/profile.d/60qt5.csh and /etc/profile.d/60qt5.sh please remove QT_PLUGIN_PATH This is a bug that prevents programs using different version of QT to run (like appimages). See https://doc.qt.io/qt-5/deployment-plugins.html that says: Note: Do not export QT_PLUGIN_PATH as a system-wide environment variable because it can interfere with other Qt installations.
You have already reported this https://bugs.mageia.org/show_bug.cgi?id=25038#c2 Sorry it got overlooked, perhaps wrong assignee (now changed). I have copied the Description above to that bug as a reminder, and enhanced its title; and mark this one as a duplicate. *** This bug has been marked as a duplicate of bug 25038 ***
