Looks like something weird is happening when the MLT consumer is stopped when the clip/project monitor is closed during application exit. I'm guessing this hang will never happen if you close Kdenlive when the project is empty? Is there anything different about the desktop environments, GPU drivers, or GPU driver versions between your two computers? There were some bugs related to MLT multiprocessing that were fixed in 22.12. If you can still reproduce this problem with Kdenlive 22.12, can you try also getting a backtrace with additional debugging symbols? You should be able to do something like: $ export DEBUGINFOD_URLS="https://debuginfod.ubuntu.com" $ gdb path/to/kdenlive It should ask you "Enable debuginfod for this session?" which should additionally add symbols to your backtrace for the libraries you installed via apt.
