file corrupted and version history disappeared

I've been working on a video since yesterday. Everything was going well until a few minutes ago when I got a message popped up saying it looked like I was having trouble editing (nope).

I refreshed the browser page and major elements of the video had disappeared, along with colors being swapped in text and backgrounds.

Version history was on, but after the refresh it had completely disappeared. There seems to be no cloud version and I apaprently have to start the project over.

I am on a MacBook Pro running Tahoe 26.2. I am using Chrome (Version 143.0.7499.193).

I have the Adobe Express app on my iPad. When I tried to open the file there last night, it was also corrupted, but was fine on my laptop this morning.

The last thing I did before this happened was to import 3 SVG files into my library. They successfully impported and I was able to place them in the project.
