How to fix the lags?

Good evening, this is my first post, I have 40 hours of playtime, but this problem only appeared today. There is a lot of lags of the transitions (when I open the bag, when the fight ends, when choosing an attack) which makes the game much too long, and it makes the game unplayable knowing that it is focused on fighting . I would like to finish the game but its becoming impossible with these omnipresent lags. if you have any issues please help me . Thanks

maybe 3d sprites if u have them

reduce screen size
