Update worked without problems, until i tried hibernation(suspend to disk) via KDE lockscreen.
For some reason Hibernation fails when triggered via KDE’s lockscreen, but still continues to work when using systemctl hibernate (which is run via Konsole while in a kde session).
When triggered via KDE’s lockscreen, the error indicates X tasks(X ranging from 47 to 54) refusing to freeze and the only kde related warning for this i could find is kwin_wayland: Failed to delay sleep: Sender is not authorized to send message (and above dbus-broker: A security policy denied :1.22 to send method call /org/freedesktop/login1/seat/seat0:org.freedesktop.login1.Seat.Hinibit to org.freedesktop.login1. I do not recall having manually messed with dbus permissions before and it was working fine before the update.
I have also already ruled-out kernel issues (tried latest 6.18.0, 6.12.61 and before-upgrade kernel 6.12.48)
PS: for some reason KDE tries to automatically log me in after a resume, which in this case had already led me to be locked-out (faillock).
