This problem also affects

  grub-efi-amd64-signed

on Focal Fossa if

  GRUB_DISTRIBUTOR

is not set to "ubuntu" in /etc/default/grub.

I stumbled across this in Ubuntu 20.04-based KDE neon, but in general it's sufficient to set GRUB_DISTRIBUTOR to a "wrong" value - the grub binary tries to load itself from a hardcoded path which ends in "ubuntu" and loading will fail and end in the grub shell.

How to add Focal as an affected version?
