Please check your nodejs version. I was facing the same issue. The nodejs version on my machine was v16.2.0. I changed it to v12.22.1. It's working now.

You can check the compatible version of node for particular angular version from here https://stackoverflow.com/a/60258560/9574445

To change the nodejs versions you can use nvm https://github.com/nvm-sh/nvm
