Impossible Search on Instagram!!

Hello, I’m reaching out for help because I’ve been having a problem with Instagram for a few days. In fact, when I go to the search bar and look for someone I’ve never searched for, no accounts are displayed; it’s as if it’s not even searching. The same goes for hashtag searches; only the ones I searched for recently work and open the page with the photos, but when I search for a new hashtag, it doesn’t search at all either. If anyone knows how to fix this problem, that would be really nice, thank you.
