Thanks for coming back to me, even though this looks like it isn't a
GRUB issue.

Yes, I do see GRUB talking to me before the above message, I get the
usual list of things that I can boot with older kernels, memtest, etc.

So it looks as if, for some reason, on restart/reboot initrd can't see
the NVME drive. I.e. the kernel hasn't reset/restarted something
necessary.
