Test runner fails on Microsoft Windows #3
Description
Context
This repo has been tested on MacOS. I'm now testing it on Windows 11 and there's an issue launching the remote WebDriver session on port :4444. TBD whether this is config-related, local-machine-related, and/or a bug in any of the underlying software. This issue is to track the diagnostics and intended to help find and document how to get the tests to run on Windows 11 (and 10 if practical).
Platform is: win32
