I think I found a fix for this. Force restart seems to have fixed it for me. From home screen, tap and quickly release volume up button. Then tap and quickly release volume down button. Then hold the side button until you see the apple logo (ignore the power off slider when it pops up). This seems to have resolved it for me going on 24 hours now. If it doesn't work for you, let me know and I have additional steps to try that I thought were unrelated.
