Help I have to much homework to do and just abandoned me

I was writing an essay and suddenly the screen when dark and me savage in the screen was something along the lines of “there was an unexpected error, need to restart” but the percentage for 2h won’t move from 0% not sure what to do. I bought it 2023 so it’s not like is the oldest thing to dye on me like that
I need to study/assignment etc. Please help!
