I am not sure if this is the same issue or not. The suggested fix, which is reported to only last for a while, does not fix the errors I get, so it may be different:
sudo rm /var/cache/fontconfig/*
[sudo] password for jim:
[jim@jim-MonsterManjaro ~]$ rm ~/.cache/fontconfig/*
[jim@jim-MonsterManjaro ~]$ fc-cache -r
[jim@jim-MonsterManjaro ~]$ cloudcompare.CloudCompare
QSocketNotifier: Can only be used with threads started with QThread

Gtk-Message: 21:14:02.806: Failed to load module "colorreload-gtk-module"
Fontconfig warning: FcPattern object weight does not accept value [40 210)
Segmentation fault (core dumped)
I am trying to run CloudCompare, but cannot get past this problem.
If it is the same, please help!
Manjaro KDE (Stable)
I have tried uninstalling and reinstalling as well.
