Disable the service as mentioned here

Manjaro won't boot after update, Failed to start Load/Save #ness of backlight:acpi_video0

Try to chroot into your system and apply: sudo systemctl disable systemd-backlight@.service The issue might be linked to a systemd service that tries to save the level of backlight for your monitor when you shut down and restores it when you reboot. To chroot into your system boot a live ISO and apply in a terminal window sudo manjaro-chroot -a (select 1 if only one line is offered)
