Kdenlive: Rendering crashed with mlt_repository_init, producer_xml and GLib-GObject-CRITICAL errors

I am trying to render a Vertical HD 30 fps video with Kdenlive. However, rendering crashes no matter what output format (GIF HQ, MP4-H264/AAC, MPEG-2, Matroska-H264/AAC, WebM-VP8/Vorbis) I choose. The following errors are logged:

I am on Arch Linux (6.3.8-arch1-1). The shared object files with the specific versions mentioned in the error log are indeed missing on my system:

$ ls /usr/lib/(libopencv_tracking|libavformat|libvidstab).so*
/usr/lib/libavformat.so@     /usr/lib/libavformat.so.58.76.100*  /usr/lib/libavformat.so.60.3.100*  /usr/lib/libopencv_tracking.so.407@    /usr/lib/libvidstab.so@
/usr/lib/libavformat.so.58@  /usr/lib/libavformat.so.60@         /usr/lib/libopencv_tracking.so@    /usr/lib/libopencv_tracking.so.4.7.0*  /usr/lib/libvidstab.so.1.2*

The following package versions are installed:

$ yay -Q kdenlive opencv ffmpeg ffmpeg4.4 mlt mlt6
kdenlive 23.04.2-1
opencv 4.7.0-12
ffmpeg 2:6.0-8
ffmpeg4.4 4.4.4-1
mlt 7.16.0-1
mlt6 6.26.1-10

I am not sure whether this is causing the rendering to crash (I am not using any OpenCV tracking for instance). I couldn't find any relevant information on the other errors.
