Hello, quick question, i have kdenlive Version 21.04.2 running on ubuntu 20.04 and for whatever reason i open up one of my projects and the playback isn't working, i press ctrl space and it just says "select a zone to play"

i press "L" and i watch the pause button instantly become a play button, and the play head doesn't move not one frame, i don't know what's going on or what to do, what do you guys think?

thank you

I have a similar case (on Windows) when pressing play the clip monitor start to play or the project monitor play 1 frame only. If not done already, please try with the AppImage to see if still happen.
