Said It Here

Why does RDCMan crash immediately upon opening?

RDCMan crashes straight to the desktop or hangs in the task manager without loading servers, persisting even after a complete operating system reinstall. This prevents users from accessing their remote servers.

I have used RDCMan on this computer (Windows 11 Pro, 25H2, OS Build 26200.9445) for accessing servers remotely for the last couple of months. One day a couple of weeks ago I came in and RDCMan crashes to the desktop. Opens, doesn't show any servers, crashes back to the desktop.source ↗

What am I missing here? Is there something wrong with RDCMan? I would have thought a fresh install would have fixed any .NET errors. Is anyone else seeing this?source ↗
