Can you reproduce the step, how you got this crash? Did this happen once
or multiple times?

If systemd dies, it will freeze and no longer reacts to any requests. So
systemctl status etc no longer working, is expected.
You should still be able to reboot in a somewhat ordered fashion via
"reboot --force"

systemd should have generated a core dump as /core.

Please install systemd-dbg and gdb and then run

gdb --core=/core /lib/systemd/systemd

The type "set logging on" and run "bt full" afterwards and attach
gdb.txt to the bug report.
