Fun House hard crash when send data to IO #10520
Description
This basic reproducer code seems to consistently cause a hard crash on the Fun House. It is a very pared down version of this project: https://learn.adafruit.com/funhouse-mail-slot-detector code
from adafruit_funhouse import FunHouse
funhouse = FunHouse(default_bg=None, scale=3)
def send_io_data(mail_value):
funhouse.network.push_to_io("mail", mail_value)
print("before send to io")
send_io_data(1)
print("after send to io")
I have tested on both of these versions and behavior is the same on both.

When the code runs it prints
before send to io

Then seems to get stuck. The USB serial and file connection disconnect after a few seconds. After several more seconds eventually the device reboots and comes in safe mode with this hard crash message:
Running in safe mode! Not running saved code.
You are in safe mode because:
CircuitPython core code crashed hard. Whoops!
Hard fault: memory access or instruction error.
