iOS 13.1.3 update

My apps won’t run nor am able to download anything from the App Store!

after I just updated my iPhone to the latest software (it’s an Xs max), at first I thought the issue was from the developer then I tried using some of my apps!

but it won’t start any, it keeps on flickering them off except for prime apps (like the ones that come with iPhone devices)

would it be just because the apps are not up to date with the firmware of the device? Or would it be something I did? I am pretty sure I did nothing.
