iPhone 14 Pro slow performance and app failures after iOS update

I’m not sure how to describe it. My phones just been trashy since the update. Pics can no longer be searched, no matter what I type in says no results found, similar problems in my files and videos. Some stuff taking forever to load other stuff won’t open, recordings crashing or not recording, predictive text gone from not working to not even trying, camera not focusing, lost goes on and on
