Comment 1 Kai Uwe Broulik 2019-05-23 15:18:17 UTC 
Dolphin uses KIO::moveAs which prompts to rename if already exists, whereas Folder View goes through KDirModel which uses KIO::rename which complains when it already exists and doesn't work when direct rename isn't possible.
I guess KDirModel should be changed?

KDirModel: use moveAs instead of Rename when editing file name
When renaming a file on the desktop to an existing filename, the operation previously failed with a generic error instead of showing the expected "file already exists" dialog. This change ensures consistent behavior with renaming in the file manager.
FIXED-IN: 6.18
