iPhone SE will freeze on last digit of passcode after powering up from a shutdown

My iPhone SE will freeze on the 4th digit of my passcode, if I'm booting it up from a shut down, restart, or software update. It will freeze with the last number I put in still highlighted. If I wait, the phone restarts on its own but the problem persists. If I force a reset, it still doesn't work. The only way I can get it to work now is if I wait 30 minutes with the phone plugged in, but I'm not sure how long that solution will last. I just updated my phone. Why is this happening? I don't want to restore my phone.
