Steps to reproduce the issue

Add article to a Category Blog
View HTML
Relevant line starts with script type="application/ld+json">{"@context":"https://schema.org","@graph":

Expected result

Relative path for schema "image" and "thumbnailUrl" includes forward slash so the relative path points to root and therefore domain/images

Actual result

Forward slash missing from schema "image" and "thumbnailUrl" resulting in relative path pointing to category and therefore non-existent domain/blog/images

System information (as much as possible)

Present in Joomla 5.1.2 and 5.1.3
