New Windows installation, project creation fails with "multiprocessing-fork" error

[spyguitar]

• I have upgraded to the latest GYB release from https://github.com/jay0lee/got-your-back/releases and I still have this issue.
  --CONFIRMED, running GYB 1.60
• I am typing the command as described in the GAM Wiki at https://github.com/jay0lee/got-your-back/wiki
  --CONFIRMED

• Running on Windows Server 2019, version 10.0.17763
• Also tested with the same behavior on Windows 10 Pro, version 10.0.19044

Full steps to reproduce the issue:

1. Download and install GYB from https://github.com/GAM-team/got-your-back/releases/download/v1.60/gyb-1.60-windows-x86_64.msi
2. C:\gyb\gyb-setup-bat launches automatically, and I enter my email address, OR
3. run c:\gyb\gyb --action create-project --email [Google email address]

Expected outcome (what are you trying to do?):

• The Google authentication flow should happen and I should be able to create my project.

Actual outcome (what errors or bad behavior do you see instead?):

• gyb.exe: error: unrecognized arguments: --multiprocessing-fork parent_pid=2484 pipe_handle=752
• at this point, I can only CTRL+C to get out, or close the cmd window

Looking at Process Explorer, 2484 is the PID of GYB.exe; it has three NamedPipe handles, two of which are called "\Device\NamedPipe\pyc-2484-0-sv13popd". I checked the discussion group and this hasn't been mentioned yet; a quick Google search indicates this might be something wrong with the way Python for Windows is implementing multiprocessing.
