Build 14316.

Neither Open Windows Defender or Scan Offline work with options through Update and Security. Same results on 2 different machines, 1 DT, 1 Laptop. Same results with OS upgraded thru WU & a clean install. SFC shows clean. All DISM work shows clean. No missing updates. Screenshots below. This is a puzzler. 4 others have reported it in Feedback. I upvoted and added comments.

Defender thru Cortana or any other search and execute works fine. Getting def updates. It's just the Settings path that is whacked out. Is there a switch somewhere I'm not aware of?

Thanks for any insights.....TC
