[Bug 1983245] [NEW] Can't change password (polkit dialog is not triggered)

[xalt7x]

Public bug reported:

On Kubuntu 22.04 even with "Kubuntu Backports" PPA I can't change
password because dialog which asks elevated rights (sudo/root password)
doesn't appear

How to reproduce:
1) Go to System Settings > Users
2) Click "Change password" and enter new password

What should happen:
1) After click on button "Set Password" user is asked for administrator password
2) User is notified that it's better to change Kwaller password as well

What currently happens:
1) Dialog disappear without any error (I didn't even see anything unusual on a terminal output)
2) User is not informed about KWallet
3) Password doesn't change

If I launch systemsettings with elevated rights
Like
pkexec env DISPLAY=$DISPLAY XAUTHORITY=$XAUTHORITY KDE_SESSION_VERSION=5 KDE_FULL_SESSION=true systemsettings5 kcm_users
or
sudo systemsettings5 kcm_users

Password changes.

I tried it on a clean install inside virtual machine.
I also tried openSUSE Leap 15.4 (which also has KDE Plasma 5.24) and password change works there.
