my project didn’t save

i was working on a project last night and naturally before i close after effects i saved it. i then closed after effects and turned off my pc. i went to open the project which showed last edited at the time i saved it and when i opened the project nothing was saved. the files imported were even gone. it said nothing about files missing or anything like that it just didnt save. it saved how i was zoomed in on the comp and everything just the files and progress is gone.
