I have the strength/boulder crash, too. Walking into a boulder (pic1) or trying to use strength outside of battle (pic2) crashes the game instantly. I´m playing on V12 Update 2 and also tried to reinstal the game, which didn´t helped . I´m now at a point in the game (Underground Sanctuary) where i can´t progress without using strength. So, here i am asking for help.
