iPhone XS Unresponsive

iPhone XS is unresponsive to launching apps via touch. It will visually show it's been pressed, as I can delete the app icons and make them shake if I press longer. The problem is I cannot open the apps. There is also a problem with the phone being unresponsive to the off/on button. I tried a force restart and it didn't work, presumably because of the on/off button not working.

Any help would be greatly appreciated! Thank you in advance.
