hmm this sounds like you tried to update /etc/cryptsetup located in your
rootfs. If so I was suggesting to update the one in the initramfs which should
be directly accessible at /etc/crypttab from the emergency shell.

The recipe is quite simple:

  - edit /etc/crypttab and and the "nvme" prefix if it's missing.
    you can figure out it's missing if the by-id path starts with
    '-'

  - systemctl daemon-reload

  - exit from the emergency shell

If that works you still need to update /etc/crypttab in your rootfs and run
"mkinitrd".
