Files blocked on Drag and Drop of Windows folder

Hello at all,

I have a Nextcloud 28.0.6 instance and when I try to drag and drop a windows folder with files inside to Nextcloud in browser some of the files inside are not uploaded to Nextcloud and for each failed file the message “Operation is blocked by access control” (not always the same files, not always the same number of files).

If I create a folder by hand, select all the files in the windows folder and drag and drop them to Nextcloud it works without problem and no file is blocked.

Is there a known problem in Nextcloud drag and drop with (windows) folders?
