When finishing the screenshot with a double click rather than clicking the enter key, and doing the double click outside of the selected area, the selection is reset and thus a screenshot with zero dimensions is taken. It then shows an error message, as in https://github.com/shutter-project/shutter/issues/487 However, after clicking the "Cancel" button in this error message, Shutter is in a state where only Dekstop capture is available while Selection and other modes, and also the tray icon menu, are disabled. However, if you then make a Desktop capture, the other modes get available again.
Steps to reproduce the issue
Use the Selection mode the zero size area, e.g. by finishing with a double click outside of the selected area.
Observe the error message and press the "Cancel" button.
Observe that only the Desktop mode is available.
