App not launching on Mac (2.13.2)

It seems something is not working on the new version (2.13.2) when I try to run the application I get the following on console

dotnet: Hosting environment: Development
Content root path: /Users/luissisamon/Documents/radzen tests/networkTool/server
Now listening on: http://[::]:5000
Application started. Press Ctrl+C to shut down.

ng-cli: ** NG Live Development Server is listening on 0.0.0.0:8000, open your browser on http://localhost:8000/ **

ng-cli: webpack: wait until bundle finished: /

And nothing on the browser, if I go manually to localhost:8000 I only get the can not connect to the server

This is not a known issue. Check for any build errors. You can also try creating a new app to see if makes a difference.

I have reverted to an old version I had on my laptop and is working fine (2.12.2) Demoing tomorrow, I do not want to risk.

I get a build error that never happened before. Even with 2.12 I can no longer launch. Any idea?

dotnet: Startup.cs(69,16): error CS1061: 'IServiceCollection' does not contain a definition for 'AddHttpContextAccessor'and no accessible extension method 'AddHttpContextAccessor' accepting a first argument of type 'IServiceCollection' could be found (are you missing a using directive or an assembly reference?) [/Volumes/InternalSD/networkTool/server/project.csproj]

This error could happen if you don't have .NET Core 2.2 installed. Is this the case? You can check that by running dotnet --version in a Terminal.

Thanks for your answer. This is what i got:

Well restarting seems to have worked. Weird.
