Extension internal error. It is a pretty strange message that appears when you try to stress files and folders (Move to Bin) on Macos Ventura.
I have been a macos user for more than 10 years but it is the first time I receive such an error message when deleting files. In the past on the older versions of macOS, when a file could not be deleted because it was blocked in a process, the error message was: “Item can’t be moved to Trash because item can’t be deleted“.

The error appeared when I tried to delete more folders and files from Downloads, by the classic method, Command + Delete. Nor with the selection of all files and then click-right and “Move to Bin” I was not more successful.

The very simple solution to get rid of this error and you can stress the files, is to pull them (drag & drop) in Bin. Went wonderfully. Click-right and “Empty Bin” to disappear from everything.

I do not know if it is a bug of the latest version of Macos Ventura, but the error appeared on a MacBook Pro when I tried to delete files and folders. As far as I know they were not in use, used by any application or process on the macos.
