Unable to boot after latest update

to see all the messages during boot, hit ESC after the system has started booting -
you might see more and that might not be the actual error

When I looked up the error you stated:

I found this:

Failed to start Virtual console Setup error message

more specifically this post:

Failed to start Virtual console Setup error message - #23 by Nachlese

apparently my advice there solved the problem back then.

So:
what is the content of:
/etc/vconsole.conf

and, perhaps related:
what is the content of /etc/mkinitcpio.conf
the HOOKS line in particular
?

these PATHs are from within chroot

I have no idea what:

could mean or what could have caused it

Perhaps it is also time for you to provide hardware info:
inxi -zv8
but this one not from within chroot, please
copy/paste, the format using </>
