Game automatically sets screen brightness to 100%

Ever since the recent game update, every time I open Sims 4 it seems to automatically ramp up the brightness on my laptop to 100%. If I minimize the game, my laptop reverts to my selected brightness setting, but bringing the game back up just ramps the brightness back up. If I press the Windows key to bring up the laptop brightness setting, it says it's still at what I set it as. I never had this problem before, and it seems the game brightness settings under Graphics doesn't do anything either.

Sounds like a stupid complaint, I know, but I suffer from light sensitivity and the the game is legit giving me a migraine because it's so dang bright!
