There should be an exception printed to the serial monitor. What is displayed?

Hardreset circuitpython
https://github.com/tuupola/circuitpython/blob/master/docs/wipy/tutorial/reset.rst

That link is from an out-of-date fork. https://circuitpython.readthedocs.io will always be the latest.

To erase the CircuitPython filesystem, use these commands at the REPL:

>>> import storage
>>> storage.erase_filesystem()

Any code/libraries on the CIRCUITPY drive will be erased, so use that with caution.
