[Q] Galaxy s4 "Unfortunately Settings has Stopped" CANNOT Figure this out! topic

i am still relatively new to hacking this device, but not to hacking in general so please bear with me. i have superuser installed on my galaxy s4 along with TWRP v2.5.0.2. Somewhere along the way something went wrong because i was no longer able to make calls. i check the hardware and everything seemed fine so v deducted that i must have done something wrong and that is what was causing the issue. Now i regretfully did a Factory Reset through TWRP and now the phone starts up to the AT&T "Welcome to your new phone!" screen. After setting everything up, wifi, language, etc. i click finish and the screen hangs for a bit, then displays a message "Superuser Granted to Shell" before crashing and going back to the origial "Welcome to your new phone!" page and displaying a message "Unfortunately settings has stopped". i can access my phone through USB since i had debugging enabled but i have no idea how to resolve this issue. Please help!
