My iPhone constantly shuts down and my apps are no longer compatible after latest iOS update

Since I updated the new iOS version 17. My phone constantly shuts down and my apps are no longer compatible. I am constantly uninstalling and reinstalling apps. I am not getting text messages. I am very frustrated because I cannot use my phone like I did before it is no longer reliable, I did not get text messages from my bank but once I deleted the app got the text messages. Something has happened with the last iOS update because it screwed up my phone.
