Okay then it’s probably worth double checking the basics again lol
- do you have both
kwalletandkwallet-paminstalled? (pacman -Qs kwalletshould show both) - is your only wallet named
kdewalletwith the exact same password as your user account? - is sddm the actual greeter you’re using? (This one’s a longshot but I’m running out of ideas 😂)
If it’s yes to all of these I honestly don’t know what to think, maybe it’d be worth trying another wallet to see if that’s any different
Idk if this is more work than you wanna go to for it, but maybe install and configure
gnome-keyringinstead and see if that works? If the same thing works with that one, great, and if not at least the problem area has been narrowed down
