if(have_rows('page_builder', $this_page)):
while(have_rows('page_builder', $this_page)): the_row();
if( get_row_layout() == 'page_content_block' ):
$this_text = get_sub_field('page_content_editor');
$this_text_plain = strip_tags($this_text);
// flexible row logic

endwhile;

I found that if you try and pass get_sub_field('repeater_page_object')->ID as the have_rows() $id parameter, it will cause an infinite loop, however, if you store these values as a variable on each loop index it works fine.
The above is an example of how I managed to get the result I wanted. This was placed within a flexible content loop in a if (get_row_layout == 'x') { } statement.
