What is the problem?
When getting to this part, virtualenv venv, this is the error I get, yes, Python is installed.
'virtualenv' is not recognized as an internal or external command,
operable program or batch file.
pip --version = pip 20.2.1 from C:\Program Files\WindowsApps\PythonSoftwareFoundation.Python.3.8_3.8.1776.0_x64__qbz5n2kfra8p0\lib\site-packages\pip (python 3.8)
What did you already try to solve it?
Started from scratch several times.
Have you tried running in safe mode and if so did it solve the issue?
serial.log or output on terminal tab at a minimum, browser error console if UI issue ... no logs, no support! Not log excerpts, complete logs.)
