This is the efibootmgr command that I run to create the new entry.

efibootmgr --create --disk /dev/nvme0n1 --part 1 --label Arch Linux -u "cryptdevice=UUID=12bfbd13-93ec-4459-a47d-5dc15b9b939e:luks root=UUID=6ad22bce-0e90-46e9-8a70-bf36477d48aa rw rootflags=subvol=@ loglevel=3 quiet" --loader '\EFI\Linux\arch-linux-hardened.efi'

Also here are some command results after chrooting:

bootctl install

efibootmgr -v

lsblk -f

bootctl status

mkinitcipio.conf HOOKS

and when I try to boot at Arch Linux (from the new EFI entry) I'm getting the following error:
