help with game prob

HI ! i started playing sims recently and since i play xenoverse 2 modded i wanted to try to play with mods on sims too and since i started i'm having fun but i'm currently strugling with a problem, i'm installing some mods and allat but for some reasons when i enter construct mode my game freezes, like i can move my mouse but i can't save can't go to menu, i do can move my camera butt it's juts impossible to quit construction mode, i looked around to see if i could get help and saw that the localthumbcache file when deleted could solve these kind of problems so  i deleted the file from my folder and at first it seemed to work i could modify my house and buy thing and etc but when i try to exit the construction mode same thing happens game freezes... Help pls..
