If you use Datashare with Docker (not the standard version), if a dark window called the Terminal displays a phrase beginning with "Windows named pipe error: The system cannot find the file specified" appears, it means that Docker Desktop, one of the 3 components of Datashare, is not working. Relaunching Docker Desktop should solve the problem.
Find Docker Desktop in your Applications or the whale icon on the menu bar of your computer and click 'Restart'.
