Please send me your broken save file at sadambober@gmail.com
That'll help and I can probably fix the save file too. Save files are here (auto_save.json or manual_saves\*number*\save.json):
Windows: C:\Users\*username*\AppData\LocalLow\Glitch Pitch\Idol Manager\data
Mac: ~/Library/Application Support/Glitch Pitch/Idol Manager/data/
