Answer 1

after try out the before solutions proposals , it worked for me

update in your package.json

"@angular-devkit/build-angular": "~0.1000.3" 

can you see here all versions.

https://www.npmjs.com/package/@angular-devkit/build-angular?activeTab=versions

check which version work with you current version from angular/core

for angular 10 work with version 0.1000.3 of @angular-devkit/build-angular
