I've had mine since December but this JUST happened to me this week. So this is STILL happening!!! THANK YOU to all who contributed below. I'll consolidate what worked for me. The one thing I have to add, combining the below, is that
1) A 15 Pro / Pro Max issue (ProMax for me)
2) Regardless of the charging hardware/type, it appears to happen when charging VERTICALLY not horizontally. So maybe it is a gyro issue partially?
Mine never woke up naturally after 30 minutes of pressing buttons (and 🫨 panicking!) This is the fix that worked for me:
* Tap volume up
* Tap volume down
* Press and hold right side button until you see apple logo
...back to normal! (for now...)
