No idea what could be causing this, but your trace there sure it's helpful when this will be looked at.

I've seen this time to time with the Core2. Having a powerfull external power seems to fix the issue for me. It happend mainly when the screen was switching on and trying to debug.

[josesimoes]

@alberk8 is this still happening with the latest version?

[alberk8]

Not have a chance to full test it this week. Quite busy :(

[josesimoes]

@alberk8 is this still happening? Haven't seen any similar reports and ESP32 have been under heavy testing, so I supposed this has been fixed...

[alberk8]

Nothing so far with the IDF 5.1.x. So closing it.
