Hello @Faraz_Firoz,
Well, it should be working, no matter it's a space in the username or in other directories.
However, your local sources aren't updated automatically with each commit being pushed in the origin repository, you must manually pull the commits pushed in the remote repository to get the latest changes. Have you updated the sources by re-cloning it or better by pulling the latest changes from the Appinventor master branch? i.e:
git pull origin master
If not, i don't expect something to change instead of what was going before.
Have you updated the sources?
If not, run the previous commit and try rebuilding.
