iPhone 10s stuck in an app, won't turn off, won't launch anything

[SHNXX]

My iphone is stuck in an app and I can do certain things like swipe down and lock, but it won't turn off.
Volume buttons work.
I can't seem to reset using hold power/volume.

Any ideas?

I had this issue last week with my iPhone X. The only thing to do is let the battery die. 🙁

NVM fixed. It randomly went into black screen and allowed me to turn it off after about 10 minutes of agony.

You can always force a shutdown with volume-up, volume-down, hold power. You need to do the first two in sequence, not holding them, and then hold the power button for quite a while

Timing may have been off, but I did try that precisely.
Nothing was seemingly working for about 10 minutes.
