@scotty65 thank you for highlighting that, I was lost in search results:)
After manjaro-chroot login to my installation, I’ve edited the /etc/default/grub file and edited the relevant line as below:
GRUB_CMDLINE_LINUX_DEFAULT="XXXXXXXXXXX SYSTEMD_CGROUP_ENABLE_LEGACY_FORCE=1 systemd.unified_cgroup_hierarchy=0"
and then sudo grub-install && sudo update-grub
and then rebooted my computer.
Now I can go back to my Monday routine, peacefully:))
