Hi there, welcome to WordPress Trac! Thanks for the report.

Introduced in [51145].

It looks like a plugin or theme changes the posts_per_page value to 0 using the ajax_query_attachments_args filter. By default, it's set to 40 in wp-includes/js/media-models.js​.

We should be able to check the value and set $max_pages to 0 too in that case.
