Remote Desktop Manager (free 2.0.6.0) has stopped working

RDM was working fine all day today. Sometime between 6pm and midnight, Windows 10 automatically ran Windows Update and it would appear something has broken RDM. On startup it comes up with a dialog box saying RDM has stopped working. Event Viewer has this:
