Google has stopped showing me in the search engine

Good morning, I have a children's storybook in Spanish, and it had always been doing well and growing, but suddenly, this week, Google decided that it will never show any of my pages again. I don't know what to do because I haven't done anything that could be harmful, and I've only focused on improving the page and uploading content. Suddenly, no matter which story you search for, I no longer appear in any search results. Not even with exact match searches. Do you know if there's anything I can do about this? It's frustrating that over a year of work has gone to waste for no reason.
