Description

Hello,
when i try to use pipupgrade with the --requirements param on Windows 10 (the same command works fine on Linux):

pipupgrade --requirements requirements.txt

it raises the following errors:

concurrent.futures.process._RemoteTraceback:
"""

The above exception was the direct cause of the following exception:

This seems to be an issue with some new versions of pip. I believe they've changed the object type for the same.
