Hello @Jack07,
I am still having the same issue as you. I have seen this happen before after installing a new build of Windows 10. I have cleared all definitions in Windows Defender and I have deleted the Software Distribution folder and I have restarted my computer. Windows Defender update is still failing. For now all I know to do is just wait and see if the issue corrects itself.
ps I seem to have the most current definition as well. I don't know why a new one is being offered and then failing. I also see the new update downloading without issue and then failing to install in WUMT.
