Collab viewer?

Hi
win 10 Ue4 4.23 last update.
Trying to use the collab viewer in Ue4. Started up a wifi network between a laptop and a notebook. Established a TCP port (7777) on both machines. Checked the firewall wasnt blocking Ue on either unit. Followed the packaging documentation. Copied the project folder to the notebook. Double clicked the packaged project on the laptop but no welcome screen as seen in 2-one person starts a server, just a scene view from 0,0,0. Looking in the level blueprint of the collab project shows nothing there. Under interacting with the collab viewer doesnt mention inserting a nav mesh, so what do I have to do to get the viewer up and running in online multiplayer mode? With the network settings I have I managed to start a multi user session without errors although the notebook is too small to allow a copy of the engine on it.

These are the errors I am getting in the output log:

​​​​​​​Any help appreciated!

Finally! Got the collab viewer working. I found a post by someone who used Visual Studio 2019 instead of 2017. That seems to have done the trick.
