now I return here to share what i have found on this problem. You cant believe it but it was due to some missing packages and I found it while comparing my installed packages with a colleague.

Error description btw was really poor and led us to really different areas to look for a solution.

So dropping here a screenshot of what packages I choosed while installing. After those installed , all came back and worked like a charm. :)

azure development
python development
node.js development
.net multi-platform app ui development
