Close Folder command does nothing in Sublime 3.2.1

On OSX 10.14.6 (18G87)
Sublime 3.2.1 Build 3207

Activating Close Folder via any method (right click in file, right click on folder in project file list, or use command pallet) results in a failure. No tabs get closed. Console error:

Traceback (most recent call last):

    return self.run(edit)
