version 6.1.1 filters do not work any more

Hi – i updated to 6.1.1
Compared to version 6.0.3 the following filters are not working as expected:
wp_get_attachment_image_attributes,
wp_calculate_image_srcset,
wp_calculate_image_sizes
The srcset is not added for some images, the lazyload attribut is incorrect and the size are not present.
This is restricted to the front page.
For this page i fetch the images like so:
<?php echo wp_get_attachment_image( 71,'full') ?>
Has something changes in 6.1.1?
Thanks for your feedback.
regards theo
