Two things I can think of:

1. Do you know if you have freetype installed? Based on the === message it seems to think it is installed and available from your Java installation. However, that installation doesn't seem to include the necessary development headers (.h files). You could try setting the environment variable AGGDRAW_FREETYPE_ROOT (see here) to the location of another version of freetype that does include the headers. I know there is a freetype-py package that might help get that installed if you don't have another way (sorry, not sure on Windows): https://pypi.org/project/freetype-py/

2. Aggdraw has not been released with a python 3.8 wheel yet so that's why it is trying to compile things from source on your machine. A new release would get rid of this error message most likely.

aggdraw 1.3.12 was just released to fix this (a python 3.8 wheel). I also created a maint/1.3 branch here on github so if we need to make more releases this shouldn't be quite as difficult. Feel free to comment if there are related/continuing issues, but more likely a new issue should be made.
