To reproduce the problem, simply create a fresh Python 3.8 environment using venv or conda and install panphon:
conda create --name panphon-py38 python=3.8
conda activate panphon-py38
pip install panphon
and get this error as soon as you import panphon:
$ python -c "import panphon"

We're hoping you'll be able to merge it and release a patch, because at the moment we have to restrict our panphon requirements to panphon>=0.19, <0.21 for the g2p and ReadAlongs/Studio projects because we still support Python 3.8, but we'd really like to benefit from the improvements you recently brought to panphon 0.21.
