I was also experiencing this issue, with a similar error message. What I found is that it was only happening for users with a restricted user role, eg. my 'content editor' role. If I try and delete the paragraphs using my user 1 'admin' role, then it works fine.
Using a process of elimination I've found that if I grant the 'content editor' the following permission, then they are able to delete the paragraph content items.
System
Link to any page
Warning: Give to trusted roles only; this permission has security implications. This allows to bypass access checking when linking to internal paths.
I was experiencing the issue with the double file extensions, eg. *.jpg.webp.
Applied the patch in #40 to 3.1.0 and it has resolved the issue for me.
Brilliant thanks for that Nilesh! I created a patch and tested it and it seems to work as expected when I add the additional content queue relationship. I'm attaching the patch in case it's useful.
