settings app crashes

I am having an odd issue with my current install. the phone was working fine but today (likely sooner, but I am uncertain as to exactly when), my settings started failing.

the problem is whenever I tap on any item in the settings menu, settings crashes. Wifi, bluetooth, about phone, anything.
logcat indicates a security exception:

I have tried deleting the com.android.settings and com.android.providers.settings folders from /data/data and that didn't fix the problem. I have tried wiping the cache and dalvik cache with no success. My next step is to re-flash the ROM, and if that fails, wipe and reflash the ROM. I would prefer to fix the problem without a wipe if possible though.

I have the Kingzone K1 Turbo running CM 12. I plan on upgrading to CM13, but last time I was on 13 I found that bluetooth was flaky (it wouldn't stay connected to my car).

Any thoughts?
