iPhone 12 Pro cannot touch screen

Do you know which app you were using when the screen froze ?

Try this Apple Support article:

Quit and reopen an app on iPhone – Apple Support

OR

Maybe you saw a "phone is disabled" message before the phone became unavailable ?

If your iPhone won't turn on or is frozen
