Updated GRUB on Arch Linux, tried fix but GRUB gives error: Symbol grub_debug_malloc not found

I posted this same post on r/archlinux but have not gotten much results. I updated Arch Linux (vanilla), but now GRUB boots into firmware.  (I am sure a lot of you guys have known this issue, and I did know about this prior to updating, but when I updated it, the fix didn't work in my environment.) I am currently posting this inside of the EndeavourOS Live environment. I have chrooted:

sudo mount  /mnt
sudo mount  /mnt/boot/efi
sudo arch-chroot /mnt

 (Replaced `` with my root partition and `` with my EFI partition because, obviously, I am running UEFI.) and I have reinstalled GRUB thanks to this post by sradjoker on the EndeavourOS Forum.

grub-install
grub-mkconfig -o /boot/grub/grub.cfg

and GRUB gives this error:

error: symbol grub_debug_malloc not found

GRUB then puts me in GRUB rescue.  As I understand it, some files are missing.  I tried this same process multiple times, but it still did not work. Is there a fix? Do I need to reinstall Arch Linux? "The latest grub package update needs some manual intervention"
