Publish Online Suddenly not displaying images correctly since 6th November 2023

Hi there,
Yesterday I tried to update an InDesign document which I'd published online.
I had to add some stuff to the document which I then published online with the changes (new publish, not over written) and it seemed to break some of the embedded images. I thought it must be the changes however I did test the back up I had which was an identical document and when publishing it online again some of the images or all of them are broken. Without making any changes in InDesign, Each time I publish online a different thing is broken or restored. (sometimes its 1 image thats broken, sometimes its all of them).

I decided to move the files to another computer which has a different version of indesign and it produced the same problem. This was on Catalina on InDesign 18.1.2 and also on ventura on InDesign 19 has the same problem.

Here is a link to the back up online publish which still appears correctly

Here is a link to the same identical document which was published online after the 7th

Note with this one I overwrote the file a few times to check if it was working again, without changing the document. Each time different images were broken.
Here's the updated page I made which is also broken

Also note here one of the big broken link boxes is actually a text box, not an image. So its not a linked object exlusive problem I don't think.

Here is a link to the back up document files

And the updated one

I originally posted the problem here

and a few people have cropped up recently (since the 7th of November) with a similar issue.
Many thanks,
