ADDITIONAL INFORMATION

Are you using the Ubuntu digiKam Snap package? If so, use our AppImage.
Snap packages use a sandbox, this package format is not suitable for digiKam.

thank you so much, Maik, for your immediate help.
Using the appimage made 8.6 work correctly and Videos are showing.
This makes me really glad for being able to use your wonderful software now.
Only still struggling to integrate the app into the desktop.
