KDE multiuser: password fail or stuck loading

Hello,

I am running the very latest and updated version of Manjaro and I am experiencing this issue:

I created a second user (tried both via GUI and via CLI) but every time I try to do login in KDE I have that 1) the password is not valid or 2) it remains stuck in loading the desktop.

The password is 100% valid and I also tried changing it from the main (admin) user.

Also I noticed that once I do login with the main user, when I logout I am not able to do login anymore and I need to reboot the desktop manager.

How can I troubleshoot this problem?

Thanks!

output from:
find $HOME/ -name ".Xauthority"

Thanks, brahma

The file is there:

[new_user@lap new_user]$ find $HOME/ -name ".Xauthority"
/home/new_user/.Xauthority

The only difference than the same file on my working user is the size (bigger for my working user).

so remove it:
rm /home/new_user/.Xauthority
reboot, and see if it helped
