Error: ext4magic Error 13 while opening filesystem

I'm trying to recover an accidentally removed directory (/home/garid/.gnupg) with ext4magic. However, It outputs following error:

$ ext4magic /dev/nvme0n1p3  -f /home/garid/.gnupg/  -a $(date -d -5days +%s)
/dev/nvme0n1p3 Error 13 while opening filesystem
ext4magic : EXIT_SUCCESS

I'm not sure what I'm doing wrong. What is Error 13? And How can I make it work?

My distro is Archlinux. My Partition table:

nvme0n1     259:0    0 476.9G  0 disk
├─nvme0n1p1 259:1    0     1G  0 part /efi
├─nvme0n1p2 259:2    0    32G  0 part [SWAP]
└─nvme0n1p3 259:3    0 443.9G  0 part /

As suggested in below, running as root outputs below:

$ sudo ext4magic /dev/nvme0n1p3  -f /home/garid/.gnupg/  -a $(date -d -5days +%s)
[sudo] password for garid:
Filesystem in use: /dev/nvme0n1p3
