I also confirm this bug. I used rufus in windows to create my bootable
USB with ubuntu live server 20.04.
I also confirm the work around to "rmmod tpm" and I'm off and running.
Thank you all for making this easy to follow!

Bug description:
Trying to loop mount ISO.
Installed grub 2.04 to flash drive in UEFI mode from 19.10
Flash drive does not boot and gives Out of memory error & no server error. Must load kernel first.
Re-installed grub from 18.04 to same flash drive using same boot stanza.
Booted without issue.
From 18.04

grub-install (GRUB) 2.02-2ubuntu8.13
from 19.10
fred at fred-Z170N-eoan:~$ grub-install -V
grub-install (GRUB) 2.04-1ubuntu12
Boot stanza that works in 2.02 but not in 2.04
menuentry "Focal Live ISO" {
set isofile="/ISO/focal-desktop-amd64.iso"
loopback loop (hd0,1)$isofile
