@Klad I need your guidance. O technical One.

So the other night, I was working on my animation. The clock struck 1am and I went to bed. This morning I wake up to work on my file before and lo and behold, it is corrupted. I am a desperate animation student on a time crunch, my final is literally due tomorrow at midnight. 

This is my file: https://drive.google.com/drive/folders/1g0bXprZ6taD4MzEMKjUrIC8xSXK85cE9?usp=drive_link

Work your wizarding magic o wise one. I NEED your help.
