Why does my dolphin crashes after doing this?

[D.I.]

I started to play the Resident Evil remake yesterday and saved a couple of states and it was working perfectly but when I tried to play today when I load any of the states it loads but then after 1 sec or 2 the dolphin crashes and it says the error is appcrash and idk why cause I played resident evil 0 using savestates and finished the game with no problem but with this one I'm having this problem and I tried with the 4.0 version but it doesnt even loads it crashes inmediately after I choose any state idk what to do I really wanna finish this game but without saving states it would be too hard for me cause I dont have too much time to play and sometimes I have to stop playing in the middle of a boss fight cause I got to do anything else and without the saving states it would take me like a year to finish the game.
