All my best,

Give this a try.................

Open Elevated Command Prompt >  Copy/paste this command line..........

"%PROGRAMFILES%\Windows Defender\MPCMDRUN.exe" -RemoveDefinitions -All

> Enter.

Then, in the same Elevated Command Prompt,  copy/paste this command line...........

"%PROGRAMFILES%\Windows Defender\MPCMDRUN.exe" -SignatureUpdate

> Enter.

Now try updating your Windows Defender again.

Tried what you are suggesting (david hk129). Still no luck. Command line tool gives the same error.
I am getting this error on my eight server 2016 installations.
Think MS need to get in to this.
