Uncaught Error prevents saving changes

I recently started received an “Uncaught Error” warning after making changes and attempting to save my scss file. Even after commenting out the changes, I am still getting the error. See debug output below.

The css in my file that was there before is getting applied correctly, but any changes I try to save are met with the error, and the changes are not reflected on the site

I had not changed anything in a while, so this might be related to the 5.6 wordpress upgrade.
