Managed to resolve this Kdenlive uses ffmpeg as the encoder so it must be built with the vpx flag in order to use libvpx media-video/ffmpeg vpx made the issue go away
Can you please test the latest version and see if you can still reproduce?

Latest version is 22.08. Since you are using a distro package I'd recommend you test and also compare with AppImage or Flatpak.
https://packages.gentoo.org/packages/kde-apps/kdenlive GenToo has both, albeit one as testing. I'll go first for 22.04.3 to avoid update problems but otherwise your version would be possible to test too.
I did now some tests with 22.04.3 . The profiles "WebM-VP8/Vorbis (libre)" and "WebM-VP9/Vorbis (libre)" are now working and produce correct *.webm files. The profile "WebM-AV1/Opus (libre)" I can not test since it is not selectable which can be due to a missing use flag. From my point of view this issue can be closed.
