This is not a bug. The application does not support multi windows. When the application starts, the backend part starts on port 3033. When the second and subsequent copies of the application are launched, port 3033 will be already used. Exactly what is described in the error.

but how is it not a bug if I am not the one opening a second window? It is the program itself opening the second window, not me

1. I open the program
2. Error prompt launches
3. I close the error prompt
4. Second MassCode window opens on its own

1. Read the comments above
2. Check what is occupying port 3033
3. Close all current application windows
4. Launch the application again
