Cannot read properties of null (reading 'bindingStartIndex')

[adamovicphactum]

Which @angular/* package(s) are the source of the bug?

compiler, core

Is this a regression?

Yes

Description

The error occurs when the library and webapp are in separate workspaces. Adding the following to the webapp/tsconfig.json:

"preserveSymlinks": true,
"paths": {
  "@angular/*": ["./node_modules/@angular/*"]
}

As mentioned in #35586 leads to:

[alxhub]

This type of error is often seen when multiple versions of @angular/core are present within a bundle, which sounds plausible given the setup described. Likely both your application and library are pulling their own instance of @angular/core.
