“Unable to create io-slave” error

I am trying to attach a file in the "Send Fax" wizard of HP Device Manager (HPLIP 3.20.6).
I am running it on Kubuntu 20.04.
In the window called "Select Files to Send", I click on the "Add..." button, and I get the error
Code:
Unable to create io-slave. Can not create socket for launching io-slave for protocol 'file'.
This has nothing to do with the specific location of the file I want to add, because I get the error before I can choose location.

First thought is permissions.

Have you tried doing this as root or with "sudo"?

I found a list of hplip commands, but I get a warning that hp-toolbox and hp-sendfax should not be run as root, and then they fail with an error. But the commands work when run with regular privileges.
Code:
warning: hp-sendfax should not be run as root/superuser.
