Aseprite Error loading file: vector too long

Hello there,

I have a problem, when I try to open my aseprite file the console says:
Bad compressed image. Error loading file: vector too long
In the file is a walking animation (10 or 11 frames, 430x530) I worked on last week at my university. The file suddenly went very big (119mb) and took a long time to save or export stuff. When I tried to open it at home, the error occurred and now I can’t open it at all… There’s a lot of work in this file and I really need it for my project… Maybe someone can help me to recover it or give me some tips on what to do now.

Thank you for your time.
