Truffle Drizzle Tutorial fails on last step 'npm run dev'

Question

I am on windows 10, using vscode. Basically finished the petshop tutorial with no issues or problems using truffle.

when I enter the command npm run dev it fails as shown below.

PS Y:\code\petshop> npm run dev

> [email protected] dev
> lite-server

internal/modules/cjs/loader.js:316
      throw err;
      ^

Error: Cannot find module 'Y:\code\petshop\node_modules\immutable\dist\immutable'. Please verify that the package.json has a valid "main" entry

}

Not sure where to go from here, nothing works. This type of error is a bit beyond me. Any and all help is greatly appreciated.

EDIT: changed screenshot to code snippet. And I realized the problem is that the 'immutable' path is non-existent in my node_modules. Still not sure how to address this. tried a cheeky npm install immutable to no avail....
