A few days ago I created a new project with Angular CLI and everything worked fine. I'm not able to create any new project now. Below is the error logs in cmd:

Here is the output from ng version:

How come this problem has occurred suddenly and how do I fix it?

I just had a similar problem, only in my case, the process froze following the circular-son download. I killed it and ran it again and it worked fine.
