"Unfortunately, System UI has stopped"

[AC Question]

Hey guys, I have an S6 Edge and yesterday i started getting the "Unfortunately, System UI has stopped"message and pressing ok made it go away only for a second. I thought a reboot would solve it but now it boots up and immediately I get the System UI has stopped message and I can see all my missed calls and messages and notifications load up in the background but the moment I press ok, it all goes away and I have my background wallpaper fading in and out on my screen, no lockscreen, no apps. I have tried deleting the cache partition. How can i solve this. By the way I'm running Android Marshmallow 6.0.1.

Your next step is probably to do a factory reset.
