Cause

 

The MarkupSafe has been upgraded to the latest version (2.1.1) which causes the error.

Resolution

If the MarkupSafe package is upgraded due to a Python package, please check if you can use a lower MarkupSafe version. Version 2.0.0 works fine. Note that the MarkupSafe version that comes pre-installed with Alteryx Designer is 1.1.1.
