I have had the same issue on multiple sites on D10 - sites on D8 are not experiencing this.
The issue only happens when logged in as Admin, when visiting the site as a regular user im able to load all the content from the load more button in the infinite view.using Views Infinite Scroll module 2.0.2
I dont have any sites on 9 to test but assuming this is a D9 and up issue?- 🇺🇦Ukraine noteboy
Just advice. Review your custom code. Can be case that you have overridden infinite-scroll.js in your theme and after upgrade that file was not updated and it causes an error
noteboy, thank you for the suggestion. I took a second look at this and found that the issue was that the custom theme on all the forementioned sites was loading an additional version of jquery as part of a library in theme.libraries.yml, I removed this and rewrote some of the custom javascript to use the version supplied by core.
