Sass compilation not working. No error information. Dreamweaver CC 20.1

I am attempting to migrate a website to Dreamweaver and am having an issue getting sass compilation to work. I am using Dreamweaver CC 20.1

I have enabled compilation on save in settings. I have specified the source and target directories for css preprocessors.

Sass compilation works without error using sass at the command line using versions 3.5.0 and 1.26.0.

Whenever I attempt to compile sass in DW I get the following error:

Image is small. Text is

Line: --

Column: 1

File: tci.scss

Erros/Warnings:

I have tried removing code from my scss file. I have tried compiling a blank .scss file. I have tried changing the file extension to .sass. I have tried uninstalling DW and reinstalling. I have tried installing Compass support. All results in the same error as above.

Any help is appreciated.

**EDIT: I am using Windows 10

I have also tried resetting user preferences as described here: https://helpx.adobe.com/dreamweaver/kb/restore-preferences-dreamweaver.html
