Not enough plastic is coming out of your nozzle.
It really could be a lot of things… a clog, temperature to low, too much friction against the filament so it is hard to pull through, nozzle is bigger than your slicer settings say.
Try one thing at a time. Good luck!
I use Garuda, which is Arch based. Pretty much every time I’ve had a problem it’s been solved by update, restart.
If you want to try and build a raw Arch system from scratch, maybe it’s still complicated, I don’t know, but there are easy Arch options these days.
