bugport-esp32
While initializing a WLAN (on an ESP32 GENERIC_SPIRAM board) with:
>>> import network
>>> station = network.WLAN(network.STA_IF)
the following error occurs:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>

Possible bug with WiFi on ESP32-S3
port-esp32
Hi all.
I'm using the ESP32-S3-WROOM-1 (N8R2 - 8MB Flash and 2 MB RAM), specifically this kit: ESP32-S3-DEVKITC-1-N8R2
I tested the STA and AP modes, in the both modes ESP32-S3 just congeals/stop to works when the WLAN is activated -> wlan.active(True)
Testing WiFi as STA mode:
>>> import os
>>> os.uname()
(sysname='esp32', nodename='esp32', release='1.18.0', version='v1.18 on 2022-05-05', machine='ESP32S3 module (spiram) with ESP32S3')
>>>
>>> import network
>>> wlan = network.WLAN(network.STA_IF) # create station interface
>>> wlan.active(True) # activate the interface
Terminating...

Testing WiFi as AP mode:
>>> import os
>>> os.uname()
(sysname='esp32', nodename='esp32', release='1.18.0', version='v1.18 on 2022-05-05', machine='ESP32S3 module (spiram) with ESP32S3')
>>>
>>> import network
>>> ap = network.WLAN(network.AP_IF) # create access-point interface
>>> ap.config(essid='ESP-AP') # set the ESSID of the access point
>>> ap.config(max_clients=10) # set how many clients can connect to the network
>>> ap.active(True) # activate the interface
Terminating...

Is it really a bug?
Thank you!
