I have a M5Stack Core Basic 2.7. I am attempting to use the SD card slot. It is a 16GB SDHC card that is formatted to FAT32. I created a simple block code in UIFlow2.0 that is:
Setup(Init Built in hardware->Init SD Card->Print(SDCard Listdir()). Init SD card is defined as:
sdcard.SDCard(slot=2, width=1, sck=18, miso=19, mosi=23, cs=4, freq=1000000)

This gives the error of:
[Errno 22] EINVAL
E (3390) spi: spi_bus_initialize(758): SPI bus already initialized.
File "hardware/sdcard.py", line 21, in sdcard
OSError: (-259, 'ESP_ERR_INVALID_STATE')

I tried adding a spi.deinit block but this doesn't even seem to be in the source code.
I have also tried the test_sdcard.py file in the uiflow-micropython repo and same thing happens.
What am I doing wrong? I have had this working on the same board and SD card with arduino but the micropython one doesn't seem to work at all.
Here is the code as well:

import os, sys, io
import M5
from M5 import *
from hardware import sdcard
label0 = None
def setup():
  global label0
  M5.begin()
  Widgets.fillScreen(0x222222)
  label0 = Widgets.Label("label0", 117, 208, 1.0, 0xffffff, 0x222222, Widgets.FONTS.DejaVu18)
  sdcard.SDCard(slot=2, width=1, sck=18, miso=19, mosi=23, cs=4, freq=1000000)
  print(os.listdir('/sdcard/'))
def loop():
  global label0
  M5.update()
if __name__ == '__main__':
  try:
    setup()
    while True:
      loop()
  except (Exception, KeyboardInterrupt) as e:
    try:
      from utility import print_error_msg
      print_error_msg(e)
    except ImportError:
      print("please update to latest firmware")
