Unable to export Audacity project-- "Audacity failed to read from a file in [name]"


I am trying to export a project I have finished working on as a WAV file. I am operating on MacOS Sierra. The project consists of many tracks, but there doesn’t seem to be errors with them. Whenever I go to File>Export>Export as WAV and try to save it onto my Desktop, it begins exporting but then I get a message that says “Audacity failed to read from a file in [name]”. I have searched for hours on how to fix this error and try to discover why my project cannot be read, to no avail. Can anyone offer some help? I am very new to this program and I need to export the file soon for my podcast.
