[SOLVED] Qt5 applications don't start, "Cannot mix incompatible Qt library"

Code: [Select]
[user@machine ~]$ krita
QApplication: invalid style override 'gtk' passed, ignoring it.
Available styles: bb10dark, bb10bright, cleanlooks, gtk2, cde, motif, plastique, Windows, Fusion
Cannot mix incompatible Qt library (5.15.16) with this library (5.15.17)
zsh: IOT instruction  krita
[user@machine ~]$ smplayer

I'm currently experiencing problems with Qt applications not starting. The solution intended for Arch Linux that I found didn't work in full, aside from uninstalling qt5-styleplugins and artix-qt-presets and artix-gtk-presets, but that breaks theming.
Anyway, this kind of problem is usually solved by an update, but no one else has posted about it and it's been almost 10 hours since I discovered the issue without an update having been issued. So I felt making a post about it might be a good idea.
