Project stuck in "building"

Can someone have a look at the above and help to know why its caught / forever loading in “Building Project”?

There might be many reasons, but that is not an example that you should be looking at in the first place. See the state of its development and you’ll understand why.

The “Fabric” initiative has now been superseded with the new FuseJS approach, which you can learn more about on our Slack community in #fusejs channel.
