You can see the reproduction here:

1. Create a macro
2. Add any output port (control or value, auto created or manually created)
3. Connect the port.
4. Remove the port via the explorer.
5. Experience nuke.

This error state persists through restarts, and is fatal to the graph.  You CAN undo to restore the graph, but David Svezhintsev reports that propagates the nuke to any graphs that have the macro embedded!

At this time the only real solution is to delete the graph.
