Bug#1100486: grub-efi-amd64: Fails to start after upgrade.

[KeyofBlueS]

Package: grub-efi-amd64
Version: 2.12-6
Severity: critical
Justification: breaks the whole system
X-Debbugs-Cc: KeyofBlueS at gmail.com

Dear Maintainer,

After upgrading GRUB to version 2.12-6, the system fails to boot, the boot menu
does not appear at all.

However, using Super GRUB2 Disk to boot and then downgrading to version 2.12-5
restores normal functionality.

Please let me know if there's anything I can do to help diagnose the issue.

Best regards.
