Segfault on Julia 1.7.2 and python 3.7.3

Empieza ejecutando mutagenesis_python.py con las versiones de Python y Julia indicadas en Windows; después, inspecciona la inicialización de Julia(...) y los frames de PyCall y LibGit2 en el stack trace informado. Se considera terminado cuando se haya identificado una causa reproducible de la violación de acceso y se haya documentado o verificado una solución para esta combinación de entornos.

I have file mutagenesis_python.py and I use python 3.7.3 and Julia 1.7.2 on windows.

import julia
from julia import Julia
Julia(runtime='C:\\Users\\racinsky\\AppData\\Local\\Programs\\Julia-1.7.2\\bin\\julia.exe')
from julia import Base
print(Base.VERSION)
from julia import Pkg
Pkg.add("MLDatasets")
Pkg.add("Flux")
Pkg.add("Mill")
Pkg.add("MLDataPattern")
Pkg.add("Statistics")
Pkg.add(name="JsonGrinder", rev="master")

running

C:\ProgramData\Anaconda3\python.exe mutagenesis_python.py

raises this error
