I do not know what causes it (UEFI firmware bug ?) nor how to fix it, but there may be a workaround : boot with the removable device path.
In the installer main menu, set the question priority to "low" and install GRUB again. The installer should ask whether to install a copy of GRUB in the removable device path. Accept.
Or : in the shell, copy the contents of /target/boot/efi/EFI/debian into /target/boot/efi/EFI/boot and rename /target/boot/efi/EFI/boot/grubx64.efi or shimx64.efi as bootx64.efi. In the installer main menu, continue without installing a boot loader.
Okay thank you for your help, I'll give this a try later when I have the time for it, and if it does not work I am just gonna give up for now. Thanks!
