Conda update requires regression to manim 0.18.1

[heafnerj]

I currently have manim 0.19.0 running in an Anaconda environment. I run an update script every morning to make sure all my environments are current and up to date. However, about two months ago the update script began requiring that I update numerous packages but that I also regress to manim 0.18.1, which I see no real need to do. Does anyone know what packages are causing this attempted regression?

Also, there are three duplicated packages installed with slightly different names (libfreetype and libfreetype6, libgfortran and libgfortran5, typing-extensions and typing_extensions). This should probably be cleaned up, but I don't know how to go about doing that.

Thanks to all!
