Are you still using the .appImage version of Kdenlive?; the one you were informed (in your previous thread) was broken in all arch-based distributions?
Indeed, informing you of the Kdenlive .appImage compatibility should be considered very helpful. It has been your choice to continue using it despite the information given, and your responsibility; please, don’t put the blame on the Manjaro community, or others, for your own apparent ignorance.
