I can see the process appear in the Task Manager and then disappear immediately. And there are no events or messages on FM Server Console that show failed authentication.
I'm running Windows 10 2004. And the client version is 14.0.4.406_x64.
Update: Under Event Viewer I can see LIBEAY32.dll is the faulting process.
Update 2: I have updated the client to 14.0.6.602 and had the same results.
