I have the same issue, with error for some primeng components:

Arg. I just posted this over on Angular's issue tracker. What's interesting is that I'm not entirely sure this is PrimeNG's issue but i guess it could be. You can view my findings over on that issue.

Update Nevermind, Angular confirmed PrimeNG is precompiling stuff instead of letting it be done on the app side.

Hi @aryanisml , you need to downgrade Angular version to 19.1.6 until this is fixed, you can use fixed version (remove ^) in package.json for this.

Thanks.
It seems the issue of Angular side.

If you look at the description of this issue you'll see that Angular team has already analyzed this and they indicated the problem is with PrimeNG, which is publishing precompiled code instead of partially compiled code.

You can see the analysis at angular/angular#60033

@mertsincan See https://angular.dev/tools/libraries/creating-libraries#ensuring-library-version-compatibility

"Avoid compiling libraries with full-Ivy code if you are publishing to npm because the generated Ivy instructions are not part of Angular's public API, and so might change between patch versions."

Should be fixed with #17731
