TeamViewer Host GUI crash / hidden on Windows 10

Hi folks,

I got an issue with a Windows 10 pro machine. Installed TeamViwer Host, lastest version and whenever it launches (at startup or otherwise) I get to see briefly the config window and then it's gone. Almost instantly after that the icon dissapears too, like it crashes.  However if I open task manager I can see the app running and the corresponding service also.

If I kill the app & service and it springs back or I relaunch it manually, the same thing happens. On the remote site, I can't connect to the machine because it's not even configured. 

I uninstalled it and installed full Team Viwer app. The same thing.

I then reinstalled Windows clean and I reinstallted TeamViwer. Same thing. Can it be a graphics driver collision? I'm asking this becuase if I connect my monitor to the dedicated Nvidia GPU I can access TeamViewer, configure it but can't remote access into that machine (team viewer client saying wait for the connection too long).If however I drop back to the Intel iGPU (integrated) TeamViwer GUI starts acting immediately (hiding or crashing).

Weird! How can I launch the TeamViwer app from command prompt with a log or something so that I can see what is going on?

Sorry: Windows 10 novice. I'm more on Linux, macOS but need Windows on that specific machine.
