On Windows: When trying to invoke process, pwntools crashes with the following error.

Could be related to #2379.

You are looking for https://github.com/Gallopsled/pwntools/pull/2310 which is only available in the beta. Try pip install --upgrade --pre pwntools to switch to the 4.13 beta. That support is very new and I'm interested if it works out for you!

Seems to work beautifully. Thanks for pointing me into the right direction!
