As already surfaced in journalctl the remount-fs.service is running into trouble:
systemctl list-units --failed
UNIT LOAD ACTIVE SUB DESCRIPTION
● systemd-remount-fs.service loaded failed failed Remount Root and Kernel File Systems
Legend: LOAD → Reflects whether the unit definition was properly loaded.
ACTIVE → The high-level unit activation state, i.e. generalization of SUB.
SUB → The low-level unit activation state, values depend on unit type.
