Windows defender error 0x80240018

I get the failure to update error as well but mine is:

Windows Defender was unable to complete the update: 0x80070422. The service
cannot be started, either because it is disabled or because it has no
enabled devices associated with it.

It ran fine for a week, then this. The service is started and I can stop,
start or restart it without problems according to the Services applet. I
dont see anything Windows Defender related in the event log when filtering
on Critical, Error or Warning.

Anyone else?
