I played Moonlit before and didn't have this error, so it might unfortunately be on your end.
I did have graphical issues with GA the first game, but none so bad it prevents me from running the game.
Make sure you run as admin and have locale in japanese at least. Check to see if you have directx of any version installed, might help.
If nothing works, at this point I think it might be better to try on another pc or laptop.
