It is almost certainly a Windows Defender update - this fails all the time.
You can check your recent updates. One method is to go to the Microsoft Update site and there will be a link there. You can tell it to ignore that particular one, all others will be OK.
You can also look for optional updates while you are there, which you wouldn’t otherwise be made aware of.
It shouldn’t be attempting to install updates for non-existent software.
As said, you can check on the MSU site for what updates have been installed and their status.
There’s a “hide this update” option in the Windows Update list of available updates. I just used it the other day for this exact reason. Note, however, that it didn’t work the first few times: I clicked “hide this update”, the update got slightly greyed out but not hidden, I closed Windows Update and opened it again, and the update was back to normal. On the third try, it stayed hidden.
