While I was drawing in Adobe Fresco, my drawing project abruptly closed and landed me on the Fesco homepage (not the iPad home screen, so the whole app didn't crash). Now on the Fresco home screen, I can see the thumbnail for my current drawing project has a white exclamation mark in a yellow circle. When I click on my project to try and open it back up, it won't open. I haven't been given an error code or anything. It just won't open. I can open other projects, but not this one.
