Boot fails here, because I didn't enter a passphrase, within a time-out. It then goes into a state where it can not be rebooted (similar to the later photo - from a different boot). Systemctl apparently can not communicate with systemd.
A non-critical fs fails to "start", due to a cryptsetup failure. It then goes to emergency mode. (Also, note that the password prompt for cryptsetup gets over-written by other, parallel jobs - e.g. fsck here. Quite confusing)
It's possible, given the error in the last few photos, that the root fs is only mounted RO now - I hadn't checked.
So now in emergency mode, systemd is running but systemctl can not connect to it - it gives a DBus error. Trying to exit from emergency mode gives further errors, including DBus ones.
ctrl-alt-del also fails to restart the machine, due to the RO / and/or systemctl being unable to communicate with systemd.
