I have same error with win10

[Prefix1802]

#5921

I am going to do a fresh win10 install(VMWare) with new node latest LTS. I will let you know if i have the same problems.

Also, update your node to the latest LTS please?

https://nodejs.org/en/

Let us know what happens.

And does npm start work?

Why are you using different versions than the one provided in the package.json ?
Try with the #5900 package.json

Try to downgrade npm to version 6
npm i -g npm@6
