"Ethernet cable unplugged"

My ethernet connection stopped working some time ago. I have been using wifi instead as haven't had time to investigate the issue further. Network preferences says the network cable is unplugged.

It is not a cable issue - have tested
All other wired devices on my LAN network are connected and receiving internet
Have run diagnostics command-D - no issues
Have tested on other accounts - no ethernet connection
Have tested on recovery boot - no ethernet connection
Am unable to update to Catalina right now due to 3rd party software incompatibility issues

Is this a hardware issue?

iMac Pro, macOS 10.14

If you mean you don't see nothing when you type your password, this is normal. Just type it and press Return.

OK I understand now. The script ran but sadly it didn't work. I rebooted.

I've tried multiple cables. All devices are connected to the router via a network switch. All other devices are connected to the internet.

Have you tried connecting the Mac directly to the router and bypassing the switch. That will tell us if it's the switch that's causing the problem.
