Cannot find module '#angular/compiler' when runnig ng serve - node.js

Question

I've updated the dependencies and since then, I've got this error message when run ng serve:
An unhandled exception occurred: Cannot find module '#angular/compiler'
Require stack:
I've tried already this solutions: Cannot find module '#angular/compiler'
But didn't work for me.
Also deleted node_modules, checkout the project again.
Is there something wrong in my dependencies or what can I do to get it running again?
This is my package.json:

Answer 1

I've found a solution.
First, check how to update:
https://update.angular.io/?l=2&v=12.0-12.0
Was updating from 12 to 13
After this, ng serve worked more or less with a few error messages that some dependencies couldn't be resolved like #angular/core
npm install #angular/core
and for all other findings
after this, all was working again
