Board will connect to 2 devices "LEFTPAW" and "RIGHTPAW" normally, and receive messages as expected. Restarting one of the connected devices once is usually OK, code will reconnect normally. After a number of restarts of a connected device (sometimes up to 3 restarts) this board will hang, and then finally crash to safe mode.
Here is the caught error immediately before safe mode:
Connection has been disconnected and can no longer be used. Create a new connection.
And the safe mode message:
You are in safe mode because:
CircuitPython core code crashed hard. Whoops!
Hard fault: memory access or instruction error.
Please file an issue with your program at github.com/adafruit/circuitpython/issues.
Press reset to exit safe mode.

Additional information
I have similar code running without issue on a Feather NRF52840. The connected devices are Circuit Playground Bluefruit boards running CircuitPython.
