Hi there ducksterduxk,
If your iPhone is freezing unexpectedly, you'll want to be sure you worked through the steps below to force restart your iPhone and see if that resolves the issue for you:
On your iPhone 8 or later, including iPhone SE (2nd and 3rd generation)
1. Press and quickly release the volume up button.
2. Press and quickly release the volume down button.
3. Press and hold the side button until you see the Apple logo.

4. If your phone doesn't turn on, follow these steps to check your hardware and charge your phone. You might need to charge for up to an hour.
5. If your phone still doesn't turn on, contact Apple Support.
You'll find those steps and some additional things to try in this support article: If your iPhone won't turn on or is frozen - Apple Support
