You can try to reset your 'sick-C' by erase your flash and burn the firmware again?
(my older m5stickC bought at 2017 .it never 'died'. I erase and burn the firmware for about 1,500 times and it never 'sicked')

@brus awesome

@frittna
can you made the green frame to blue?The default icon is blue.

maybe your compiler has some error(I only used arduino and uiflow,you can try with it)🤔

Great!

@m5stickfreakler Try to set the longpress time shorter.

from m5stack import *
from m5ui import *
from uiflow import *

setScreenColor(0x222222)

buttonA_LongPressed = 0
buttonB_LongPressed = 0
buttonC_LongPressed = 0
longPress_ms = 600
# or shorter
longPress_interval = 100
#==============================
# Your code here

My earth unit can work on stickC with analog reading.

(Maybe is G33)

#define analogpin 33   //maybe it's 32

I suggest you to use internal antenna because it's portable and not easily damaged.
