The error is occurring in Conda.jl while trying to install Anaconda Python, not in PyCall per se. (If you `add Conda` and run `using Conda; Conda.update()` you would presumably get the same error.) In particular, the Miniconda installer seems to be having network problems.

Possible workarounds: (1) Try using Miniforge instead of Anaconda by setting `ENV["CONDA_JL_USE_MINIFORGE"] = "1"` before building. (2) install your own Python, and tell PyCall about it by setting `ENV["PYTHON"]` to the path of `python.exe` before building.
