Confirmed. AutoMask on the track header-> click analyze -> crash. Opened issue https://invent.kde.org/kde/kdenlive/issues/192
Solved. https://invent.kde.org/kde/kdenlive/commit/50e1cb6304294eaa871a53acc776d1392bc5771c Automask cannot work on tracks so the button analyze is disabled if effect is applied on a track.
