After the update of the "switch" game, it crashes upon entering the game, which needs to be fixed

3500 days of single-player save files. After updating the game, an error occurs upon entry. I hope it can be fixed as soon as possible. This is my save file from three years of playing, and I'm feeling very down because of this issue. I love this game so much, and I hope you can optimize the "Switch" version more. It's really important to me
