Error 5 is EIO or I/O error. My first thought was if you are using USB 2.0 because those sometimes have power problems (that would explain an I/O error). Then I looked at your log and it appears you are using 2.0.
If I'm right, I suggest disconnecting every USB device that you don't absolutely need and trying again. (The drive did pass a previous diagnostic test telling us that it was working.) If that solves the problem, I suggest using a USB 3 drive or using a **powered** USB hub.

following this guide . I have previously ran badblocks, which
returned zero errors; I am also sure the disk is not mounted:
$ findmnt /dev/sdb
$ findmnt /dev/sdb1
Whenever I try the initialisation with cryptsetup I get this same error:
$ sudo cryptsetup -y -v luksFormat /dev/sdb1
This will overwrite data on /dev/sdb1 irrevocably.
Are you sure? (Type uppercase yes): YES
Cannot wipe header on device /dev/sdb1.
Command failed with code 5: Cannot wipe header on device /dev/sdb1.
dmesg is not reporting anything out of the ordinary:
