SevenTasks not loading + system tray bug

Since 1-2 days, SevenTasks doesn't want to load :

file:///home/mir/.local/share/plasma/plasmoids/io.gitgud.wackyideas.seventasks/contents/ui/main.qml:516:23: Type Task unavailable

file:///home/mir/.local/share/plasma/plasmoids/io.gitgud.wackyideas.seventasks/contents/ui/Task.qml:35:5: Cannot assign to non-existent property "windowTitle"

And also, since like 1-2 months, the system tray entries don't show up until either a new system tray entry appears (like discord's system tray) or i hide & unhide a system tray entry.

However, as for the system tray issue, i'm probably sure that i'm missing a dependency, as i had uninstalled plasma package and installed plasma-desktop instead later, so i'm most likely missing a dependency, since when i build compile.sh and install_plasmoids.sh, it says that KF6Plasma and Qt6QmlCompilerPlusPrivateTools are "not found" (even tho i do have kf6 and qt6 installed on my computer)

ps: incase you need to know the distro i use, it's Artix Linux OpenRC
