ESP32C3
MicroPython version
MicroPython v1.25.0 on 2025-04-15; LOLIN_C3_MINI with ESP32-C3FH4
Reproduction
import machine,time
def wlan_connect(ssid='MYSSID', password='MYPASS'):
import network
wlan = network.WLAN(network.WLAN.IF_STA)
if not wlan.active() or not wlan.isconnected():
wlan.active(True)

pass
print('network config:', wlan.ifconfig())
wlan_connect('XXX', '12345678')
adc5 = machine.ADC(machine.Pin(5))
print(adc5.read_u16())
Expected behaviour
MPY: soft reboot

Additional Information
It seems that there is a conflict between the WiFi of esp32c3 and ADCBLOCK2. This error occurs when initializing just after power-on, but it becomes normal after pressing "Ctrl+D". However, it is not completely normal on v1.23.0

Additional Information
This a dual USB C board, I saw closed issues with this, txpower=17 did not work, tried both usb ports, no change. Tried WPA and no security on AP, no change. Other ESP32 and ESP32-S3 boards connect to AP fine. Almost decided to use ESP32 for project but some dumb ass decided to make the HSPI miso pin 12, which is a strapping pin.
Also tried all other 1.24.1 ports in the generic esp32-s3: 4mb flash and Support for Octal-SPIRAM. No errors were seen on any of the ports. This does usually fix WiFi issues. Am able to preform scan() properly. Probably similar to my issue #15602
