npm start not working in Electron project

Question

After cloning the repo for a particular electron project, I ran npm install after deleting the existing node packages and then ran .\node_modules\.bin\electron-rebuild.cmd, as instructed in the readme file. This rebuilt successfully and I proceeded to run npm start. I was then met with the following error -

{ Error: spawn C:\WINDOWS\system32\cmd.exe ENOENT
    at _errnoException (util.js:1024:11)
    at Process.ChildProcess._handle.onexit (internal/child_process.js:190:19)

  cmd: 'ampy' }

Things I have tried -

• Have tried re-building the project with the .\node_modules\.bin\electron-rebuild.cmd command
• Ran npm start directly in cmd instead of VS code terminal by openings cmd in admin mode assuming there was some permissions error. This also threw the exact same error.
• Have also tried reinstalling node modules.
