This output is definitely good. Something else must be going wrong. At the moment, I'm thinking it might be your configuration.
Try a default config:
vs +new -sc c:\temp\new-config-dir
There is a sample Visual Studio 2019 project you can test with.
Project>All Workspaces...>Sample Workspaces>VS2019.sln
If you are able to open this sample Visual Studio 2019 solution, then try yours. Depending on what happens here hopefully I'll have a good idea of what the problem is.
