Crash into the HardFault_Handler

[Antavatech]

Hi, received my new feather M4 express and trying to run one of the sample codes from your website. I keep receiving the error below:

You are running in safe mode which means something unanticipated happened.
Looks like our core CircuitPython code crashed hard. Whoops!
Please file an issue at https://github.com/adafruit/circuitpython/issues
with the contents of your CIRCUITPY drive and this message:
Crash into the HardFault_Handler.

I have tried reapplying the circuit python bootloader "adafruit-circuitpython-feather_m4_express-en_US-4.1.2.uf2" but still receive the same error. The only lib copied over is neopixel.py, thanks.

huh can you try circuitpy 5.x (the latest release) https://circuitpython.org/board/feather_m4_express/

Hey, I tried that today and it's working. Also, I ordered 2 FM4Ex and tried the second one today. Same error message when using CircuitPython 4.1.2, but is now working with 5.0.0-beta.3.
