Error trying to run WebUI after installing from source on mac

[rp-walsh]

Hey everyone. Followed the instructions to build WebUI from source here.

Everything was fine until I tried to launch. I can successfully run

> dotnet run --project ./src/WebUI/WebUI.csproj

OR

> dotnet run --project ./src/Api/Api.csproj

but not both. When running the second command I get

Using launch settings from ./src/Api/Properties/launchSettings.json...
Building...
fail: Microsoft.Extensions.Hosting.Internal.Host[11]
Hosting failed to start
System.IO.IOException: Failed to bind to address http://[::]:8080: address already in use.

Any help here would be greatly appreciated, thanks!
