Description

Steps to reproduce:

Build fails because there is some issue with type declarations for @angular/aria/tabs and @angular/aria/listbox.

Environment

• Angular: 21.1.0
• CDK/Material/Aria: 21.1.0
• Browser(s): Chrome
• Operating System (e.g. Windows, macOS, Ubuntu): Windows 11

Do you see this error in your app or is it only on Stackblitz? I tried creating a new app with Angular 21 and importing the same symbols and it worked fine.

@mvukic @crisbeto It seems error only in Stackblitz. Sometimes works, sometimes doesn't. If I start to see error I cannot find ways to fix it: only create new app.

Stackblitz is only for minimal reproduction. This error happens in my local systems (Windows 11 and RHEL 8) in new project and in and existing project and my GitLab pipeline (where everything is downloaded from scratch each time).

#32673 should fix it in this week's release.
