ng build fails with 'Cannot find module @angular/core' after ng update to v22 #34709

Command

build

Is this a regression?

• Yes, this behavior used to work in the previous version

The previous version in which this bug was not present was

21

Description

After running ng update @angular/cli @angular/core to v22, ng build fails immediately with Cannot find module '@angular/core'. The project built fine on v21 before the update. Clearing node_modules and reinstalling does not fix it, and the error appears before any compilation output.

NOTE FOR LABELER: this issue is about the devkit area. Please apply the area: devkit label and set the Backlog milestone.

Minimal Reproduction

1. Create a new Angular app on v21 with ng new repro-app.
2. Run ng update @angular/cli @angular/core to v22.
3. Run ng build.
4. The build fails with Cannot find module '@angular/core'.
