Hi! A very similar error here. Except that it doesn't manage to generate the session key. If I disable security, there's no problem; everything works. But with security level 2, I can't find a way to make it work.
It performs the getStep0Request, then the sendConfig, and responds with status 133.
I'm using a ESP32-D0WD-V3 (revision v3.1)

`Send Wi-Fi scan command to device

I've noticed that this error only happened with the Android 9 phone. I'm not sure if it's the phone itself or the OS version. I tested on Android 8 without any issues, and newer Android versions work fine too.
