I2C Error 19

[Flow]

i have an M5Stack Core 2 with ENVII sensor (Temperature and Humidity). I have not managed to get it to function using Blockly. Error message I2C bus error 19.

Running 1.85 version with UI Flow 1.7.5.

Any help would be appreciated.

Simple code to test ENVII - I get two possible results

1. white screen with nothing on it

or

2. I2C BUS ERROR 19

Code

from m5stack import *
from m5stack_ui import *
from uiflow import *
import time
import unit

screen = M5Screen()
screen.clean_screen()
screen.set_screen_bg_color(0xd37272)
env20 = unit.get(unit.ENV2, unit.PORTA)

label0 = M5Label('Temperature', x=22, y=45, color=0x000, font=FONT_MONT_24, parent=None)

screen.set_screen_bg_color(0xffff66)
while True:
label0.set_text(str(env20.temperature))
wait(10)
screen.clean_screen()
wait(3)
wait_ms(2)

I have found that connecting the ENVIRO module to the Core 2 causes the M5 to lock up. White screen and nothing else.

Is the issue with the module or software? Is there a Driver issue?
