iOS 18.0.1 apps not working

I have an iPhone 15 pro running iOS18.0.1. Since I updated the phone almost all my installed apps are not working and won’t even open this includes all my important ones such as banking apps and apps for networking and house items.

I really need the apps to be working and its does not appear to be an app issue as they all do the same thing.

I have used apple phones since they came out but this iteration of iOS has been the worst.

i have also noticed the drain on the phone battery is worse as well
