KDENLIVE suddenly crashes on launch

the app crashes upon launch in the middle of a project… I don’t know why, I don’t remember changing or updating anything and everything worked just fine up until 2-3 days ago.

I’m on Fedora 42

launching via terminal shows all sorts of failures to load certain things like openGL, all the plugins, and something to do with the graphics pipeline but it’s well outside my area of expertise so not sure what to do about it.

There are numerous issues with Kdenlive on Fedora due to the distro’s own packaging. Please try the appimage version.

The dev team is currently working on fixing this together with the Fedora maintainers but there is no ETA when this will be solved.

(See my reply to your post on r/kdenlive)

I use the flatpak actually, not Kdenlive Fedora. so browsing the forum someone suggested to remove anything to do with Kdenlive and reinstall it. seemed to have resolved it, it’s launching again…
