Hi @JoeSz, try adding this new systemd-hibernate-resume.service service file to your dracut config:
/etc/dracut.conf.d/resume.conf
add_dracutmodules+=" resume "
install_items+=" /usr/lib/systemd/system/systemd-hibernate-resume.service "
Then rebuild the initramfs with sudo dracut-rebuild.
This worked for another user in this thread: Can't hibernate after udpate and systemd-vconsole-setup fails - #2 by BluishHumility
