All of my FOM progress got deleted 💔

I play on Steam Deck, if that changes much. It's not very often that I log in, but I've been meaning to come back to the game since 1.0 is dropping.

I opened my game and there was no continue button 😭 Has this happened to anyone before or is there a simple way to fix this? I wasn't crazy far in the game, but I was far enough to where I don't want to start all over again.
