Fixing my search bar admin finding WordPress

Hi everyone, what’s wrong with the wordpress image search bar lately? I can’t search, just type 1-2 letters and it immediately comes up empty, even though I know the file exists, and when I write an article to find the article, this function doesn’t work. Strangely, it’s never happened before, it’s only started happening to my website for almost 2 weeks now. Is there any way to fix it?
