That, to me, immediately makes the update suspect. Do you remember
what was updated? The kernel? Keyboard utilities or data? Any
LUKS-related packages? Was a new initramfs generated? Anything else
that might possibly be relevant for the early boot process?

Are you able to download bootable live/rescue media and boot from
that, then try to open the LUKS container from within that
environment? That should allow you to experiment more, since you will
have a fuller environment than the early boot environment. If it works
from within a live environment, then at least you know that it's
something about your installed system, not the data on disk as such.

I strongly recommend that you make at least a header backup, if you
haven't already, just in case something goes further wrong.
