Solved kdenlive avfilter effects not functioning

Sometime in November or so, (seemingly all of) MLT's avfilter effects on multimedia/kdenlive stopped working. I can add them to audio but they have no effect. Note that the 'not available' plugins do not show up in the plugin view at all.

MLT effects. avfilter effects have 'avfilter.' preprended to them.

kdenlive --mlt-log debug
amdgpu: os_same_file_description couldn't determine if two DRM fds reference the same file description.
If they do, bad things may happen!
Could not detect package type, probably default? App dir is "/usr/local/bin"

I want to add a reply here for anyone who experiences this. It appears the issue is with Kdenlive upstream. It is broken on Arch Linux, Void Linux, and Flatpak. It has been broken for a while and is still not fixed.
