Failed to login using a valid password on SDDM after screen was locked

Hi guys,
So, I just found out that sometimes I cannot unlock the SDDM after the screen was locked automatically. Below, I attach the output of journalctl and other things that might help. Any help is appreciated.

Re: Failed to login using a valid password on SDDM after screen was locked

This might not be even relevant, Are you using a non-english keyboard? I have a spanish keyboard and SDDM by default loads the US keyboard layout. Id your password contains any sign (which it should) maybe SDDM is getting the wrong symbol. Here is the wiki section covering it

I made a bow to not perpetrate the meme, so I don't RTMF people, and I don't even say the name of the distro unless I am asked direclty.

Actually, this issue is only happening when I use a user that is created using systemd-homed. So, I decide to use useradd for now. We can say that it has been solved but I cannot update the title.
