Hey!

On a system where it works, I get:

# grub-probe -t abstraction /usr/share/desktop-base/futureprototype-theme/grub/grub-16x9.png
cryptodisk
luks
gcry_rijndael
gcry_rijndael
gcry_sha1
lvm

When it doesn't work:

# grub-probe -t abstraction /usr/share/desktop-base/futureprototype-theme/grub/grub-16x9.png
lvm

As the initial reporter, the systems where it works are installed
since quite some time where the system where it doesn't work is
installed only since a few days.

Adding -vv, I see that in the working case, grub-probe says:

grub-core/kern/disk.c:196: Opening `hostdisk//dev/sda'...

But in the non-working case, I don't have that, but:

grub-core/kern/disk.c:196: Opening `hostdisk//dev/mapper/nvme0n1p3_crypt'...

Maybe Grub doesn't like NVME disks?

When it works, it starts with:
