It looks like you're missing a file, so you might want to try a clean reinstall. Simply delete that current version of the game, and download it fresh here from itch.io. Make sure you set aside the "dlc_wedding" file before you do. Check that the reinstall has the "archive.rpa" file in the "game" folder, then try it again. Hopefully that works!
