Hey! So sorry you're going through this. I'm not quite sure what the issue is, if I'm being completely honest, but I have had luck with other games by deleting the game completely from the Itch.Io folder in my files.
As in, going into the Local Files, finding the Itch application, then finding "When Twilight Strikes." After that, I usually redownload the game and try again. Again, this has worked for me before, but I don't know if it will for you <3
