Error moving temporary file to Caches folder on MacBook

What does this mean.“CFNetworkDownload_ThWZKo.tmp” couldn’t be moved to “Caches” because either the former doesn’t exist, or the folder containing the latter doesn’t exist. I get this error and a blank trying to load message

I found the solution.


Close Messages.


In Finder, navigate to your Library > Containers and look for the folder called "#images" and delete it.


This worked for me.

I also have this issue recently. Images panel shows grey boxes instead of images (even after searching), and if I click on a grey box to "add the image" to the text, I get a "couldn’t be moved" error. So, I tried your advice. Still grey boxes, even after a search, but now instead of it saying "couldn’t be moved", if I click on a grey box to "add the image" to the text, it now displays the following (could not share image).
