My screen goes dark when I´m in game

but when I go into setting in game the brightness returns to normal or when I leave the game and change to a chrome tab or something, the loading screen is alsodark as well as the main menu, this just started happening today, the only new cc I installed were mirrored dreams rapunzel hairs 1 and 2 and the rapunzel dress and the merida hair. Could this be caused by a mod?
