tkinterhtml is untouched since Feb 27, 2016 https://pypi.org/project/tkinterhtml/#files
This issue might be tackled in pypa/setuptools#1788

my params:
setuptools-50.3.2
python 3.9.0
pip 9.0.1

Edit: Talked to Snooz (Q4.2020)
A fast workaround could be:
One could use python 3.8 or fork the repo and exclude tkinterhtml (it is not essential) and install it with pip from source

tkinterhtml is removed from the current release. it was too buggy.
