Importing framework_is31fl3743 causes CircuitPython core crash#3

I tried setting up my macropad to run macropad_backlight.py, but the line from framework_is31fl3743 import IS31FL3743 appears to cause the CircuitPython core to crash. This is the full error message:

Auto-reload is off.
Running in safe mode! Not running saved code.

You are in safe mode because:
CircuitPython core code crashed hard. Whoops!
Fault detected by hardware.
Please file an issue with your program at https://github.com/adafruit/circuitpython/issues.
Press reset to exit safe mode.

Any advice?

    After some digging around, I've found that triggering any exception by any means nets this result... which isn't typical for CircuitPython. Is there something preventing the exception handler from running, perhaps?

    Running help("modules") reveals that framework_is31fl3743 is not a module that exists. Does it need to be manually installed somehow?

    Using the firmware.uf2 from that repo works! This likely indicates a failure in the build system.
