What happened? ionic serve --lab now opens a new browser window but doesn’t load the app. If I use http://localhost:8100 I can see the app in the browser, but --lab has stopped working and I HAVE to enter http://localhost:8100 I’ve downgraded but now even v3.19.0 is broken too.

Ionic serve & ionic serve --lab have not working in 3.19.0
