If it crash right after you open the game it might be double files of something in your particle folder.
Open your FeralHeart folder, media -> particles and if example have two of example aura, or maybe even three of them. Delete two of them, example aura_0 and aura_1.
If it crashing whike you're playing, and keep crashing when you chose a character. Try to wait like 5 minutes before you try again.
Still nothing, try to restart your computer, and if it still doesnt work then uninstall FeralHeart, remove the folder and all files in it and then install it again.
