Package: grub-efi-amd64-bin <https://packages.debian.org/trixie/grub-efi-amd64-bin>, grub-efi-amd64-signed <https://packages.debian.org/trixie/grub-efi-amd64-signed> Version: Current Debian Testing ISO
There's a bug in Debian Trixie (Debian Testing) aka. Debian 13 where GRUB is completely invisible (black screen) on my ThinkPad T440p using an Intel HD 4600 integrated GPU. You can still interact and guess what option you'd need to choose and it will then boot the system just fine, it's just GRUB that's affected.
