The previously indicated bug has landed in this stable update as well.
I have been able to restore my system from BTRFS snapshot,
to change branch to stable and upgrade without issue till this point,
when the upgrade killed my system again.
([Testing Update] 2022-11-09 - Plasma 5.26.3, Python, KDE-git - #10 by osiixy)
With @openminded we have tried to find the culprit without luck.
The only reappearing pattern is an error about missing libcrypto.so.3 during chroot rescuing before downgrading the system (and of course the “Key slot open failed” error at boot time unlocking) .
Some fact of my system:
mkinitcpio.conf
MODULES=(nvidia nvidia_modeset nvidia_uvm nvidia_drm)
BINARIES=()
FILES=()
HOOKS=(base udev plymouth autodetect keyboard keymap modconf block plymouth-encrypt filesystems resume keyboard)
