Problem opening saved file

Hi, I have a little problem opening my file, the software had crashed. luckily I had saved it the day before, so I still had something to work with, but when I tried opening my file it said “unable to load” :413: error: is missing link 0 (iteam000). I don’t know why it won’t load because I had saved it before the system crashed.
is there any way i can recover the file.
