I am getting a crash with cairo blend using place holders:

:::: USING TRACK COMPOSITING:  "frei0r.cairoblend"
ASSERT: "pos >= 0 && pos < int(m_allTracks.size())" in file /home/farid/git/kdenlive/src/timeline2/model/timelinemodel.cpp, line 265
Comment 4 Jean-Baptiste Mardelle 2024-03-22 12:51:48 UTC 
Thanks for your report and sorry for the bad experience. The attached project file is unfortunately unrecoverable, as there are no tracks in the project. This is a case that I have seen a few times in the last 5-6 years but since it's a very rare bug, hard to fix.
I have however pushed a change so that at least, Kdenlive won't crash trying to open such files, but will directly propose to open a backup.

The initial project corruption might be related to this but not sure:

Please try with the actual version 24.08.3. This crash, when opening an existing project should be solved now.
