Welcome to Android Central! Does this happen in Safe Mode as well? https://support.t-mobile.com/docs/DOC-28997

Had any luck yet, I have the exact same thing going on and it's making me crazy! No problem until I updated to Android 6.0

Let us know if you stumbled onto the fix!

I am having the same issue and I tried safe mode. There is no different outcome, still unable to set screen lock and only swipe is active. Also, one General > Security, I get an error message if I attempt to open Security settings.

If it's happening in Safe Mode, then it sounds like a problem with the firmware. Which carrier are you on? If it's Verizon, you could use their Repair Assistant to reinstall the firmware.
