Comment 8 for bug 1775131

networkd-dispatcher, on its own, does not configure or control network interfaces. It listens on d-bus for events from systemd-networkd. So this is almost certainly a symptom rather than the cause of your interface stability issues, *unless* you have given networkd-dispatcher some script to execute that controls interfaces. If that's the case, you should probably not do that, since it would cause all sorts of hard-to-debug issues :)
