I have similar issue.

Here this property used to be defined as:
@Input() options: any[];:

But then in next commit it changed to
@Input() options: string[] | string | undefined | null;

So now if anybody who has setting "strictTemplates" is true it will be failing
maybe to change it to something like "unknown" instead of string or any

yea I'm also trying to use a custom interface under the p-cascadeSelect's [options] attribute, but I'm being told only string[] | string | undefined are accepted

Angular 16.1.2, PrimeNG 16.0.2

Until it's fixed, you can Ctrl+click (on Windows) on options and change string[] to any.
