This version expects " ‘libQt6Qml.so.6(Qt_6.11.2_PRIVATE_API)(64bit)’ ", but tumbleweed has only version 6.12.
So, I can’t install kdenlive anymore.
Welcome to the community 
Please try the AppImage or Flatpak.
Never used an AppImage or Flatpak before.
Why is Kdenlive using a library with a private extension? In this way it feels if this app is leaning towards closed software.

AFAIK, Qt is a for-profit organization/company but has an agreement to provide some of their libraries free of charge for FOSS development. Names may be misleading in this case
