Using the official V1.22.2

Reproduction

This is a very complete program using:

• Ethernet
• 4G
• 2 serial ports
• WiFI
• BLE

Expected behaviour

Not panic attacks

Observed behaviour

The same code used on 2K devices on V1.18 and V1.19

Now trying V1.22 (the official image) in few seconds running I get this.

But don't know where to look

Wifi connection issue as well, it seems something is wrong with the ESP libraries, right?
