Can't enable cheats in my game

Can't enable chats. it worked briefly after the new update then back to not being able to enable them. i was using a fresh save. i dont have mods i dont have any expansion packs and have few dlcs. i use crtl+shift+c and try "testingcheats true" ou "testingcheats on", the cheats are enable message doesnt appear, but the cheat bar becomes blank and below a rectangular blank box appear (it looks similar to the box when you start typing something on the internet and sugestions appear bellow on it but in this case is blank too). i tried using other popular cheats like "motherlode" and "rosebud" and got the same result
