@juliank: I was affected by this bug when upgrading to 22.04.1 from 20.04 at the weekend. (originally installed as 18.04)
Unfortunately the system did *not* auto-recover.
Manually picking the previous kernel options from grub gave the same "error: out of memory."
I was able to recover the system through live cd -> decrypt -> chroot -> MODULES=dep.
This got me to initramfs on next boot, where I was able to `cryptsetup luksOpen` and mounting /root manually before continuing the boot.
After getting back into the system, a final `update-initramfs` gave me a cleanly booting system.
I've seen various other reports in Google of similar problems on Dell XPS 13 hardware like my own with 22.04.
