'TypeError: Cannot read property 'NormalModule' of undefined

I am working on a big project and I cannot run it anymore because of this error:

When I run npm run serve

 ERROR  TypeError: Cannot read property 'NormalModule' of undefined
TypeError: Cannot read property 'NormalModule' of undefined
    at VueLoaderPlugin.apply (/Users/<user>/muso-ninjas/node_modules/vue-loader-v16/dist/pluginWebpack5.js:44:47)

    at processTicksAndRejections (node:internal/process/task_queues:96:5)

Please help me because I am stuck and I would like to go with my project.

As suggested in link from the first comment, I deleted node_modules, replaced the node-sass in package.json with "sass": "^1.26.5" and ran npm install but it didn't work.

Then I repeated the steps and removed package-lock.json as well.

This helped and the app was served properly
