crash when installing pip package after uninstalling conda package on windows

[cjdoris]

On Windows the following sequence of commands

using CondaPkg
CondaPkg.add("python", version="==3.10.2")
CondaPkg.add("numpy")
CondaPkg.rm("numpy")
CondaPkg.add_pip("six")

gives the following error from pip install six (with no other info):

ERROR: failed process: Process(`'.....\Temp\jl_9sNBLw\.CondaPkg\env\Scripts\pip.exe' install six`, ProcessExited(3221225781)) [3221225781]

Here is an example CI run: https://github.com/JuliaPy/CondaPkg.jl/actions/runs/9786963389/job/27134814649?pr=135

Replacing numpy with jsonlines works fine.
