Using latest git master or 25.04 branch, Kdenlive crashes on Mac (only tested on arm) when trying to use the OpenTimelineIO export feature. Crash seems related to casting to AnyDictionnary, and does not happen on Linux nor on Windows. Latest binaries to reproduce the issus can be found here: https://files.kde.org/kdenlive/unstable/ <details><summary>Crash log</summary> ``` ------------------------------------- Translated Report
