iphone 13 pro to power off. The power off slider can't slide to right

Perform a Forced Restart on the phone. Follow the instructions very carefully, as this is a bit tricky. You may need to repeat this several times. Do NOT attempt to move the slider to Off during this process.....you have to keep holding the Side button for another 15-20 seconds until the Apple logo appears in the center of the screen. Then, you can release the Side button.
