Arch Linux

I try to install with the following commands.

modprobe dm-crypt
modprobe dm-mod
cryptsetup luksFormat -v -s 512 -h sha512 /dev/nvme0n1p3
cryptsetup open /dev/nvme0n1p3 cryptroot
mount /dev/mapper/cryptroot /mnt
cd /mnt
mkdir boot
mount /dev/nvme0n1p2
mkdir boot/efi
mount /dev/nvme0n1p1 boot/efi
pacstrap -i /mnt base base-devel openssh linux-headers linux-lts linux-lts-headers linux-firmware networkmanager network-manager-applet wireless_tools wpa_supplicant dialog nano
genfstab -U /mnt > /mnt/etc/fstab
arch-chroot /mnt
passwd
nano /etc/locale.gen
HERE remove # en_US.UTF-8
locale-gen
echo LANG=en_US.UTF-8
export LANG=en_US.UTF-8
ln -sf /usr/share/zoneinfo/US/Central /etc/localtime
hwclock --systohc --utc
echo HOSTNAME > /etc/hostname
nano /etc/hosts
nano /etc/default/grub
HERE set GRUB_CMDLINE_LINUX="cryptdevice=/dev/nvme0n1p3:cryptroot" Can change nvme0n1p3 for UUID
nano /etc/mkinitcpio.conf
HERE in the hooks section, add encrypt after block
mkinitcpio -p linux-lts
grub-install --boot-directory=-boot --efi-directory=/boot/efi /dev/nvme0n1p2
grub-mkconfig -o /boot/grub/grub.cfg
grub-mkconfig -o /boot/efi/EFI/arch/grub.cfg
exit
cd ..
umount -R /mnt/boot
umount -R /mnt
reboot
HERE remove USB LIVE

But then reboot appear error device UUID.
The UUID show is the UUID from cryptroot.

Why can't I install the arch on my laptop?
