Micropython ESP32 S3 UART pins

Question

Hi I am currently connecting a SIM800L to an ESP32 s3 using pins rx: 18, tx: 17

and running this code:

from machine import UART
id = 1
gsm = UART(id, 115200)

This then returns the error for both id=1 and id=2:

Guru Meditation Error: Core  1 panic'ed (LoadStoreAlignment). Exception was unhandled.

Can't use id =0 as it is reserved for REPL

Here is the pin diagram of the esp32-s3
