IPhone X - “Notification Cancelled” message & Apps won’t open

I accidentally called 911 while trying to turn my alarm off this morning. Realizing my mistake, I cancelled the call to emergency services. They did call me back so I obviously didn’t cancel quickly enough. Now the problem with the phone is that the only thing it would display is a black screen with “Notification Cancelled”. I was unable to do anything including restart by holding both the side button and either volume button for a good 30 seconds. Somehow, I don’t know how, but the Notification Cancelled message was still there but it looks like it was a separate window? If you swipe up it displays the open apps, it was there so I tried to hold it down to swipe it up and get rid of it. Nope now it’s the only thing I see and can’t do anything again!
Whlie the message was in the background I was able to see the home screen, swipe left and right to see the apps but nothing would open. I touched everything from messages to settings and they kind of flickered and that was it. I did have a Text come through and I could pull that down to read it, but nothing else.

Software was updated yesterday.
