Images corruption

Hi,
I’ve a problem with my website.
A couple of months ago I noticed that, in some older posts, some images where no more visible.
I checked in the media library and I found out that the image was still present, but somehow not working:
– the thumbnail was blank (I also tried to regenerate it);
– in the media library I can correctly see the image

-I can see the image while editing the post but, on the published page, the 5th image is not visible

The original code is:
<img src="https://www.followthewhitedog.it/wp-content/uploads/2018/09/Resegone_05.jpg" alt="" width="1500" height="1000" />
but it’s not showing.

The crazy thing is that if I reupload the image I get the same problem.
The only way that I have to fix the problem is recover the original image, copy the content to a new file and save it with a different name.
Once I upload it and replace it in the post it works.

WP is updated to the latest version (5.3.2–it_IT) and it’s happening also with the latest post.

I’ve checked the DB with my provider and it’s working fine.

I don’t know what to do…..

I’m using these theme:
