I think previously if there were multiple separate applications running sst start then you'd get asked to specify a new port but just now (on latest version) it bombed out with

ok, cool, ta

Opened an issue for this (@thdxr assigning it to myself as I need to make some port changes for the browser console) https://github.com/serverless-stack/serverless-stack/issues/958
