I start my reply by saying that I had the same issue on my ASUS TF300T (Rooted). Running Cyanogen KitKat 4.4.4. During a PlayStore update, one of my Antivirus Programs stated "An Issue With....". Issue resolved thru scanner, but no longer access to Android Settings.
Here's what I did....(If you have a Systems Program to do/access the same, it's worth a shot). I opened my Avast AntiVirus, went to App Management, scrolled to previously reported "problem app". Selected "System Info". This took me to the app in the Settings (yes, the App Info part of Settings). I did a "Clear Cache", followed by "Clear Data", followed by "Force Stop", ending with "Uninstall".
I then used the same Avast method to select my "Settings" program. Doing as much as done with previous app (except Uninstall----Do Not Look for or try to Uninstall). Clear Cache and Force Stop. Afterwards.....Reboot Device.
Now, since my tablet IS rooted, I also went to my TWRP menu, and did a "Permissions Fix". I don't know if this solved the problem, or if the problem was already solved thru Avast. I will not guarantee that any of this will work for you, but it may work for some.
