swaylock does not accept my correct password and fails to unlock

[Oleander]

Hello,
has anyone had any problem with swaylock/swaylock-effects recently? They don't 
accept my correct password when trying to unlock.

I use the following lockscreen.sh and system.scm:

@example
#!/bin/sh

# Times the screen off and puts it to background
swayidle \
timeout 60 'swaymsg "output * dpms off"' \
resume 'swaymsg "output * dpms on"' &

# Locks the screen immediately
swaylock --clock --indicator --screenshots --effect-scale 0.4 --effect-vignette 
0.2:0.5 --effect-blur 4x2 --datestr "%a %e.%m.%Y" --timestr "%k:%M"

# Kills last background task so idle timer doesn't keep running
kill %%
@end example

Also, do you have any suggestion to improve my code? One thing I never figured 
out is how to log in to the system automatically without a display manager.

I found this config https://gitlab.com/mbakke/guix-sway-example/-/tree/master 
but I don't know if it still works and I need some time to study/understand the 
code before merging some of it into my config without creating a mess.

Thank you
