Realme GT7 Pro Screen freezer problem

about a month after i purchased it my Realme GT7 Pro received an update, but from that point on when I unlock the screen the touch screen freezes completely, forcing me to hold down the power button to activate Google Assistant or Activating the emergency call and then going back are the only two ways to unlock the phone other than the fingerprint, which is activated when the screen is off. How can I fix this?
