System randomly freezes possibly after sleep

It usually happens after some time since waking up from sleep.
Previously (couple weeks ago) I had Manjaro installed on the same disc - no freezes.
Currently I’m using nvidia-open-dkms drivers, freezes happens on both linux and linux-lts kernels.
inxi -Fxxc0z:
journalctl -b -1 | grep fail:
Some other errors from log file:

In the end I uninstalled nvidia drivers (reverted back to nouveau) through nvidia-inst + removed «nvidia_drm.modeset=1» parameter in «/etc/default/grub».
Then I installed nvidia-dkms and all needed headers through pacman + uninstalled nvidia-inst.
Now everything seems to be working fine; at least there are no freezes.
