[KDE Plasma] Lock screen does not unlock user

[kuroni]

I am on Arch Linux, and I just installed nordic-kde-git 2 days ago. Everything is working like expected except for the lock screen; for some reason the lock screen is using Breeze's. Reinstalling the theme doesn't work at all.

Upon inspecting using /usr/lib/kscreenlocker_greet --testing, I think there are issues with the Nord's lock screen not being able to unlock properly.

Breeze's lock screen (kscreenlocker_greet exits upon entering the correct password)

Nord's lock screen (kscreenlocker_greet does not respond to password input)

Update: I downgraded everything related to plasma to version 5.24, and the lock screen is working fine now. Probably some sort of API deprecation was carried out.
