Iphone 10 touch screen frozen after update to IOS 15.5. Hard reset does not solve the problem

The screen on my Iphone 10 is frozen after update to IOS 15.5. Doing several hard reset does not solve the problem.

Tried to restore using Itunes, but it will not allow me to once Find is on in Icloud. But I cannot turn it off since the screen does not work. And it is not possible in ICloud on line either. Since the phone is on. Cannot power it off without the screen working.

Can someone help?
