I just realised your report isn't about cryptsetup being the problem and you never reach the initialramfs shell.
Your report that the last thing you see is "my system gets stuck at "Booting, Loading initramfs" tells us the kernel isn't starting. Those messages come from GRUB when it loads the kernel and initrd.img into memory.
I'm wondering if the recent Intel microcode updates and related kernel patches could be responsible? Can you tell us what CPU the system has?
