Touchscreen doesn't work after updating IP11 into iOS 16

Hello there,

I have literally a crisis. The touchscreen of my phone has been broken since I have yesterday updated my phone into an iOS 16. The phone works as usual, but the touchscreen acts like crazy: it can't interpret properly the commands, I can't use the keyboard, insert the PIN code to unlock the phone (I have to use two fingers and use a lot of strenght to write anything), I have the issues with swiping, unlocking, the phone is literally unable to use.

Can someone tell me what could cause these problems and how to get rid of it? I did the hard reset and I have reset all of the settings, it hadn't worked.
