After updating to the latest grub I re-ran grub-install
sudo grub-install --target=x86_64-efi --efi-directory=/efi/EFI --bootloader-id=gruband regenerated the config and after rebooting faced the "calloc not found" screen and was dropped into grub rescue. I rebooted into a live CD and tried re-installing grub which didn't fix it but after rolling back to the previous version (2.04-7-x86_64) and reinstalling it rebooted just fine.

Not sure if I'm doing something wrong or what other debug info is relevant but figured I should report the issue. Reading a few things online it might be related to the "BIOS boot partition" not being updated or something? Not sure I don't know a lot about grub...

Same happens on my laptop. Tried to fix it with grub rescue / seems broken / can't read the partitions.
Luckily (or unluckily) I have two options to boot from (my BIOS calls them: "Grub" and "[hd/partition name]") and if I switch to the second one, that one still works.
I vaguely remember that back when I installed grub, I used 2 methods of [stuff / MBR / efi?] in parallel because I thought to myself: "Well, if one breaks....". It is possible that I forgot how to update one of those 2 grubs properly and that's now the (broken) default. Don't have time to figure out what I did to my laptop a year ago or how it broke and / or fixed whatever is happening now, but I had no idea what "efi" was and still don't, so whatever I did was probably in the archlinux wiki and involves installing a redundant copy of grub stuff to wherever it is on my PC which does not support that uefi stuff.

Happened the same on my desktop while reinstalling GRUB over windows 10 default boot.
How i got this error
boot into a live CD, and run `lsblk` command
Output

Mount drives
mount /dev/sda6 /mnt
mkdir /mnt/boot
mount /dev/sda1 /mnt/bootmkdir /mnt/home
mount /dev/sda7 /mnt/home
chroot into mounted system
arch-chroot /mnt
Install Grub using following command
grub-install --target=x86_64-efi --efi-directory=/boot/EFI --bootloader-id=GRUB --recheck
grub-mkconfig -o boot/grub/grub.cfg
How i fixed error "symbol 'grub_calloc not found"
mount EFI partition to /boot/EFI before installing Grub
mount /dev/sda1 /boot/EFI
grub-install --target=x86_64-efi --efi-directory=/boot/EFI --bootloader-id=GRUB --recheck
grub-mkconfig -o boot/grub/grub.cfg
