I am trying to update a project to Angular 18, but I get this error when I tried to build:

Platform is Windows 10. I have installed the latest nodejs (v20). Then I followed the installation manual:

I looked at this question.
Can I use Node JS 20(LTS) but use an older version of Angular 13.3.0? Reason being our Angular code base has been developed over the years, too big(complex by so many folks who are no longer here), public facing. Currently we are on Node JS version 16 and Angular version 13.3.0. We run everything in Docker container in Cloud. Very first time when I changed the Node JS version to 20-alpine and set legacy-peer-deps as true)- I just got very few errors. But the moment I started using Angular CLI 17.3.9 and changed package.json(making changes for Angular JS 17.x.x)-I am having over 4500+ errors. Around 1000+ binding NG8002 and remaining all other errors.

I want multiple themes for my vendors. I created multiple environments to achieve this.

I recently created a project using Angular and Laravel. As part of the cleanup process, I deleted the node_modules folder to remove the cache. However, when I tried to reinstall the dependencies using npm i, I encountered an error. see image
