On real device if i save a project and then try to load it pack it says "..loaded successfully.." and then immediately crashes the playdate asking to restart the device. I get that even with saving and loading the default empty project regardless of the title.

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!

It's still crashes in the very same way, although it doesn't ask me for the file name to save the project into.

I currently have 2 projects and it crashes on both, here they are: Jam-05.json and Untitled.json

Ummm....

For now your data can be read and played.

I'll try some operations.
