ESP Now Master/Slave examples in Arduino IDE not working on ESP32-PICO-KIT D4 V4.1

I'm loading these into two different (master/slave) ESP32-PICO-KIT D4 V4.1 development kits and get the following error on the serial monitor in the Arduino IDE for both of them:

Brownout detector was triggered

Any idea why this is happening?

Thanks

With the words about brown out detected that might mean power issues? I run ESP32's from a powered hub when connected to my computer.

Thanks you are absolutely right.

The pc I was using had 2 front usb ports it didn't work on.
The 3rd front USB port that you can quick charge from didn't give the same issue.
It worked fine.
