Anything else relevant? import in pollyfills.ts: /* Load $localize onto the global scope - used if i18n tags appear in Angular templates.*/ import ‘@angular/localize/init’; and package.json: “@angular/localize”: “^10.0.10”, But in other hand, I’ am still not using $localize in typescript and in HTML to implement the new i18n translation. I still keep the previous implementation for i18n translation. Using $localize will be the next step after getting rid of the this issue/error.

Glad you got to the bottom of it!! Thanks for working with me on this.

I would say that you must update those peerDependencies directly. The Angular framework peer dependencies should update themselves automatically when using ng update @angular/core since it contains information about how to do that. But if you have a library that has a peerDependency, it would be up to you to do the update manually.
