Video Move/Copy fails in Bridge 2020
If a video is selected (last in a move block or selected for copy), the move/copy fails because the video is open in the DyanmicLinkMediaServer.exe (error discovered in File Explorer). Apparently, the file is opened in the media server used to sort of play the file (it is a poor video player).
The move/copy fails and must be done with file explorer externally. I don't recall encountering the issues with previous versions, but you must have the video file selected for it to manifest--the last in a selection or individually.
Also, the media player does not support HEVC Main or Main10.

Update: it was necessary to terminate Bridge to move the video file--deselecting the file did not close the file handle is my guess. After terminating Bridge, it was possible to move the file. With Bridge open, it the move would fail with the open in application error.
