I was unable to recreate this with Python 3.7. The issue seems to be exclusive to Python 3.8

We only officially support python 3.7, I know there's various issues with other versions of python / wxpython. That being said, the error itself looks like it could be a library issue in the requests package.

I'm assuming you're back up and running by now since you mentioned it was working in 3.7. Additionally, were close to being able to package a linux binary build using AppImage, please see #2410. :)
