I don't know if Windows Defender is contained in this list of Windows 10 apps, but wouldn't hurt to look:
[Guide] How to Reinstall All Default Built-in Apps in Windows 10 - AskVG

Unfortunately it is not included

I read in some other forum that removing update 'KB931099' from Windows Update and redownloading it would basically reinstall Windows Defender, but in my list of installed updated, it is not included lol...

Yup, a repair from boot media would correct those corruptions - once Windows is running a restore will not overwrite the corrupt permissions as those files are read-only - it has to be from PE.
