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

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
> pet-shop#1.0.0 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....
