'Unhandled exception in event loop' (WinError 995)

[fohrloop]

Steps to reproduce

• Python 3.8.2 32bit on Windows
• Using IPython 7.13.0
• Calling pathtub.ensure(folder)

Rootcause

• Seems that this is related to Python 3.8, IPython or prompt-toolkit 3.x. See
  • Python.org: Issue 39010
  • GitHub/IPython: Issue 12049

Workaround

Downgrade prompt-toolkit to 2.x

python -m pip install -U prompt-toolkit~=2.0

Just added this as documentation for the problem. Seems to be fixed with the prompt-toolkit downgrade.
