Hi there! If it crashes after the window, that means your computer isn't running the game in Japanese locale. The Livemaker engine only runs on computers in Japanese locale, which is rather annoying, and sadly something I am unable to rectify. Here is a helpful link on changing the locale of your computer! I hope this works and you're able to keep playing!
hello, if you didn't get pass it or weren't able to play the game, i advice you to download this https://pooi.moe/Locale-Emulator/ and to do what they tell you in this site. i tried it and it worked for me so i hope it'll work for you as well :)
