Sorry for the late reply.
I updated the software to version 1.0.2, which includes a data-loading check logic.
If it still doesn’t work after you try it, please send me the song JSON file.
Thank you!
When you download the 1.0.2 link it still says 1.0.1 in the game data. Are you sure you zipped the correct folder? Maybe that's why it's still crashing.
