Data path ".builders['app-shell']" should have required property 'class'. 2020 Update - node.js

Question

Have tried every single option in StackOverflow forums and others, no luck.
Tried and Didn't work
npm uninstall #angular-devkit/build-angular
npm cache clean -f
npm install #angular-devkit/build-angular
Deleted the node_modules folder and ran npm install, did not work
Have tried to uninstall and install #angular-cli
Most answers are from last year or with a much older version of angular that I am using. Please advise
While trying to deploy using build --prod these are the errors I am getting

Answer 1

Your #angular/cli and #angular-devkit/build-angular versions don't align.
Make sure they align. It's generally safe if they reflect the version of the rest of your #angular packages (10.0.4). So update them to:
"#angular-devkit/build-angular": "~0.1000.4",
"#angular/cli": "~10.0.4",
Then delete your node_modules folder and rename your lock file.
npm: package-lock.json -> package-lock.json.old
yarn: yarn.lock -> yarn.lock.old
Run npm install or yarn install and build your app.
If everything is ok you can remove the old lock file package-lock.json.old or yarn.lock.old.
You should generally update Angular only with ng update as this might run important migrations.
