XYplorer MP4 files in Preview-pane not working

Hallo,

I always worked with Windows-7 and I used XYplorer as my standard File-manager
Now i switched to Windows-11 and I noticed that when i use XYplorer and i want to view and play MP4-files in a preview-pane, that video did not play anymore
Probably a DLL is missing or something else, but i do not know how to fix it.
The only thing i want is to play video-files (MP4 files) in a preview-pane.
It worked always using Windows-7 but not anymore using Windows-11
Can anyone help me with this problem?
I always use Xyplorer as a portable application

Have you tried their forum ?

Yes, i tried their forum, but i find no result
I think a DLL is missing, for i used to see what Gspot find in the Mp4 files and i got the message:
H.264-Mpeg4-AVC

I scanned a MP4-video with the tool: Media-Info and the result is showing in the attached screenshot
