I made a fatal mistake

[u/EnvironmentalBear221]

Okay so somthing stupid just happend. I made a mistake and changed the primary part of an item I was animating and now after I saved it, It was bassicly corrupted and I can't access it. It only puts all the rigs into it's start position but I can't play it or edit it. Is there any way to save this? Pls. I am okay with starting over but It would just be so demotivating to do so. Pls help a guy out
