Environment
Provide version numbers for the following components (information can be retrieved by running tns info in your project folder or by inspecting the package.json of the project):

• NativeScript-Angular: 16
• Angular: 16

Describe the bug
Using Angular 16 which uses Typescript 5 and updated TSLib renders custom activities unusable and does not allow the app to start. Refer to this chat

To Reproduce

Update Typescript to 5, TSLib 2.5, Angular 16. Use custom activity as stated in Nativescript Docs

Expected behavior
App to run normally

Sample project

Additional context

Run tns info and inspect the project's package.json to confirm the Angular 16, TypeScript 5, and TSLib 2.5 versions. Reproduce the failure using a custom activity as described in the NativeScript docs; done means the app starts normally and the custom activity is usable without the reported class-not-found error.
