I believe the following mentioned bug below has returned (for some hardware?).
I located the thread :< Update snapshot 20240918 causing "screen locker is broken"problem
@mrmazda bug report here :< 1230870 – kscreenlocker crashes with pam 1.6.1-4.1 on X11 when pam_pkcs11 is installed
I have uninstalled the pam_pkcs11 package and added a lock. I power cycled the machine.
Screen locking now is functional.
Please discuss about the need or security issues if any related to removing the pam_pks11 package.
It is being installed by default on New Tumbleweed snapshots.
Thanks
