It now gets past that point, but hangs shortly after on a spinner. Not seeing any specific errors in the console. Probably just not going to happen with this app, I'll have to use VM instead :(
Seeing as how login was successful, it's likely that an implementation of WebSocketCreateClientHandle is not needed, but just to be sure you could use the native winsocket.dll from a Windows installation and see if it changes anything.
Another thing you could try is installing the .NET framework using
$ winetricks dotnet472
Also, this likely won't help but you could also try
$ winetricks d3dcompiler_47
Could you attach the console output here? Just do
$ wine "MediRoutesHost.exe" &> log.txt
