Why after migrating angular from 8 to 9 i'm getting exceeded maximum budget on scss files

Question

I migrated my Angular project from 8 to 9

When i execute the command ng build --prod

I'am getting multiple errors on scss files similar to the following :

ERROR in Exceeded maximum budget for /Users/HASSEN/IdeaProjects/my-anuglar-project/src/app/navigation/sidenav-content/sidenav-content.component.scss. Budget 10 kB was not met by 51.9 kB with a total of 61.9 kB.

I don't want to increase the budget limit in the angular.json file because it's unreasonable since i didn't modify any of those scss files.

      "buildOptimizer": true,
      "budgets": [
        {
          "type": "initial",
          "maximumWarning": "5mb",
          "maximumError": "6mb"
        },
        {
          "type": "anyComponentStyle",
          "maximumWarning": "6kb",
          "maximumError": "10kb"
        }
      ]
