Solution

  • UPDATE: This issue is permanently solved by the new official update of NGRX v17.2.0. Here is the original issue about this: https://github.com/ngrx/platform/issues/4275

    I got exactly the same error, while I worked on the angular update on our project. Finally, it seems like the problem is with the latest Typescript v5.4.2. I just downgraded it to v5.2.2 and it works properly.

    I will do a more detailed investigation later, I just would like to let you know to solve your blocker issue right now.
