Hi Emmzyfrosh1,
Thanks for coming to Apple Support Communities for help with your frozen iPhone X.
A force restart should resolve this: Force restart iPhone.
Be sure you are following the steps for your model:
"Press and quickly release the volume up button, press and quickly release the volume down button, then press and hold the side button. When the Apple logo appears, release the button."
If it still isn't working, there could be a problem with the buttons: If a button or switch isn't working on your iPhone or iPad.
Have a fantastic day!
