Kadenlive crashes (latest build on Windows) opening this small project

anyone has na idea about what is causing the crash?
this is the project: www.wcn.it/crashes.zip

Same for 23.08.4 on Linux. Very strange indeed …

Starting Kdenlive from terminal and loading the .kdenlive project file results in this output:
