illustrator not working

Hi I've been working on making presentation panels in Adobe Illustrator, but the last time I was working on it, I accidentally reset my computer before or while saving. Since then, I can't open it again. I get two errors:

1) Illustrator could partially read the file. We recovered as much as possible, etc.
2) Acrobat PDF File Format is having difficulties. Expected a dict object.

I'm confused by this since I didn't do anything regarding making or importing a pdf. Is there any way to rescue my presentation for this corrupted file?? 

here is the file link: https://drive.google.com/file/d/1GG6uhSghHiLl4AGjOer908mZI2pAT7eU/view?usp=sharing
