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
