The Schematic workflow failed. See above.

Can anyone help me with this error, every single time I'm trying to create a new project I'm getting the same error.

First, open your command prompt as Run as administrator there you can install angular using the command npm install -g @angular/cli then it will install globally in your PC. when you try to install the angular into PC using cmd you might open regular cmd , here is the fault that we have to open the cmd in administrator mode then you install your angular. After finishing installation you can run angular by creating a new project using the command ng new first-project then it works fine and you can start your project by npm start or ng serve both will work.
