Plymouth not loading themes on Arch, falls back to three boxes and question marks

I changed the spinner theme image in plymouth to add a custom background, and I tried to load it on boot. I have changed /etc/mkinitcpio.conf to add the plymouth hook, and run plymouth-set-default-theme -R spinner multiple times. [My plymouth debug log](https://paste.ubuntu.com/p/3p3hTQtTH9/) When I try to test the theme using commands plymouthd plymouth --show-splash It shows up correctly. But during boot, three boxes are shown near the bottom, with question marks above. I have tried the same procedure with spinfinity theme, with no luck. I can't figure out what is going wrong? Some help please!
