After upgrading to angular 12, app is throwing run time error "Uncaught TypeError: i is not a function"

Recently I upgraded angular app to 12 version, ng serve and ng build works fine.

Pakage json for custom webpack
 "@angular-builders/custom-webpack": "^12.0.0-beta.0",
"devDependencies": {
"@angular-devkit/build-angular": "~12.0.0"
}

After moving code to prod getting run time error like below and it's difficult to find out the root cause
