I am behind a firewall and WIndows Defender always fails with:
Windows Defender was unable to complete the update:
0x80040154. Class not registered.

What do I need to do to fis this?

Are you on a corporate network?

If so, ask the WSUS administrator to enable the class of updates for Windows
Defender.

Alternatively or additionally--go to Windows Update--Windows Defender
definitions should be offered there.
