ERROR device '/dev/mapper/root' not found. skipping fsck. (LUKS)

Hi

I followed the Installation guide together with this guide
where I have LUKS on my root partition.
I installed GRUB as bootmanager.

after rebootin, removing the USB with the .iso. and booting the drive that says GRUB (I dualboot with win10)
I get the GNU GRUB menu and boot into arch linux I get the following error

ERROR: device '/dev/mapper/root' not found. skipping fsck.
mount: /new_root: fsconfig system call failed: /dev/mapper/root: can't lookup blockdev.
  dmesg(1) may habe more information after failed mount system call.
ERROR: Failed to mount '/dev/mapper/root'on real root
You are now being dropped into an emergency shell.
sh:can't acces tty: job control turned off

I am pretty sure I did every step. This is my second attempt, same error.
It should promt me for the passphrase for decrypting the root drive but it doesn't
I tried both  busybox and systemd didn't change anything.

what did I do wrong? if I need to provide more info let me know. I just don't even know where to begin looking

What does your mkinitcpio.conf look like (assuming you're using mkinitcpio)?

for HOOKS I have

HOOKS=(base systemd autodetect microcode modconf kms sd-vconsole block sd-encrypt filesystems fsck)

I also tried with busybox-based initramfs earlied
I checked after regenerating. They were still there

Your log is from a busybox initramfs. If this was from before, that's fine, but if it's recent, it would indicate that you're not rebuilding the correct initramfs.

What does your bootloader config look like?
