My saved work doesn't show up!

It’s my first time using Harmony Essentials, I just started using it 2 days ago.
Before when I used to save my work, everything would be fine. I would open my saved work and everything would be exactly how it was when I saved it.
But this time, after I saved a scene that I had been working on yesterday, I opened it up from my files, but my work isn’t showing.
All my layers are still there and functional, but the ARTWORK doesn’t show, not on Drawing or Camera view. My colors in the Palette aren’t there either, the only color it has is “Vectorized Line.”
I need help asap, because this was a really hard project I was working on and I really wish all of my work hasn’t been lost!

Thanks to whoever it may concern! :slight_smile:
