Is it just me or did kdenlive broke for you too? I'm on an Archlinux based system and just updated the system. A few hours before update kdenlive worked. Update was not small, so its hard to tell the exact cause. I've tried to downgrade kdenlive, but same issue. I use Linux for a very long time now, but still get lost with errors like these.^^ Any idea what I should do? Does it work for you?

I get this on start (I reset the configuration files too):

$ kdenlive --version
kdenlive 24.08.1

$ kdenlive
