Error -  export 'ɵɵdefineInjectable' was not found in '@angular/core'

Root Cause - when we inject the service at both places in service @Inectable({providedin:root}) and in module provider also , then we face this error.
@Injectable({
  providedIn: 'root'
})
export class NgxAuthService extends UserAgentApplication {}

and in module we are registering service in provider as below.

providers: [
        { provide: MSAL_CONFIG, useValue: config }, NgxAuthService, 
    { provide: WindowWrapper, useValue: window }
      ]


Solution - replace above  service class code as below.
@Injectable()
export class NgxAuthService extends UserAgentApplication {
