Ah, yes I saw all the comment suggestions and was hoping a fresh reinstall would work for you.
Did you format before reinstall? Definitely seems like fstab issue dropping you into initramfs that would need some manual intervention.
A format and fresh install should totally resolve this (assuming installation options and selections are sound).
What does ‘ls /dev/sd*’ ran from shell show you?

Good thing for you, that’s terrible OpSec.
