Hello,
I have problems:

Use KDE neon. I updated the system. Kdenlive no longer works. I can not get around the "timeline" and not the "file tree".
Someone knows why?

Sorry: what is the problem?
Sometimes resetting configuration by renaming ~/.config/kdenliverc or ~/.local/share/kxmlgui5/kdenlive helps...
