Testing cheats true messing up mouse sensitivity

I removed my mods so it’s not the mods I removed overlays I’ve done everything and I’ve noticed that the second I turned testing cheats on the mouse sensitivity is so high that the game is unplayable . In CAS I can’t create a sim anymore because any slight movement makes a huge difference to the sim. I can’t edit them anymore. And in live mode the second I twist the camera it just goes in a huge circle each time. And when I try to turn testing cheats off , it doesn’t do anything I have to completely restart the game . Also I like playing with cheats, it’s sooo annoying. Is there anything I can do to fix thisss?
