Have you tried deleting the node_modules folder and then reinstall the dependencies?
I'm not sure if it solves your issue but it's something I do often when everything else fails 😅

I think the problem is with your node's version, downgrade the version and try.
I use v11.10.1

Duplicate of #7251. The error is triggered because cmd isn't in your system path. The short term solution is to put cmd in your path by adding C:\Windows\System32\ to it.
