I'm not sure why this error comes. I think you should try to run Angular application by : ng serve instead of ng serve --open .

I think the issue is because of an environment variable of your system path is missing . Add "C:\Windows\System32\" value to your system PATH variable.

Glad it works. Did you check my second point. I think because of your system configuration it is not working. Otherwise ng serve --open command is correct.
