Hey:
I have never seen anything like your errors with @agular/core and various primeng services.

That said, can you please show your package.json. While your at it also show your angular.json, but I'm hoping the answer in you package.json.

Hey:
Per StackOverflow suggestion:

deleting node_modules folder and running npm install seems to solve the issue.
