Luis,
Sorry that you are seeing this issue.
1. Can you please switch to a new workspace, replicate the issue with scaffolding and send us the .log file located at /.metadata/.log for further investigation?
2. Do you see any other jobs apart from “Initializing model project” running in the Progress view? If yes, then please send us a screenshot of the Progress view to help us get a visual.
