Hi, I'm now unable to load my Kdenlive project because the program immediately crashes when I open it due to some invalid transitions. Is there a way I can load a Kdenlive project that disables transitions? Thanks.

If you work with Linux: Please try with the current Kdenlive AppImage version 19.04.1b to see if there are any packaging issues https://files.kde.org/kdenlive/release/

If the crash still occurs can you upload your .kdenlive project file somewhere?

Yep, this happens on the AppImage as well.

I've gone ahead and created a bug report which includes the kdenlive file that causes the crash:
