iOS crash when running with release flag: Can't find variable: __metadata

Simply copy steps from here: https://nativescript.org/blog/upgrading-tips-for-angular-10/

npm i -g @angular/cli // You could be needing to prefix sudo on GNU/Linux and other Unix-like OSes.
npm i -g nativescript // You could be needing to prefix sudo on GNU/Linux and other Unix-like OSes.
npm i -g @nativescript/schematics // You could be needing to prefix sudo on GNU/Linux and other Unix-like OSes.

ng new workspace
cd workspace
ng add @nativescript/schematics --skipAutoGeneratedComponent

// start apps:
npm run ios --> this runs fine
npm run ios -- --release   --> this will cause error below

Any idea why? Tried to search for solution but can't find any. Happens to my existing project as well after upgrading to angular 10. Right now I can't seem to deploy the iOS app due to this issue.
