GRUB keyboard lay-out has changed

Hi all

Out of the blue, my keyboard lay-out in GRUB has changed.

I was unable to decrypt my drive (LUKS) as it did not accept my password (no key with this passphrase).
Rebooting the device and pressing 'e' at the GRUB menu (to change GRUB configurations) allowed me to test my password.
I then noticed that my keyboard lay-out had changed from AZERTY to QWERTY.

My guess is that some update (I did do an update & upgrade yesterday) changed or reverted my GRUB settings.

What's the best way to fix this?
