Your log shows you are using ffmpeg 6.0.1. The 6.x versions of ffmpeg were released for Jellyfin 10.9. Jellyfin 10.10 and 10.11 would prefer to have ffmpeg 7.x. My first suggestion would be to upgrade to the newer ffmpeg and see if that helps.
If that does not work, see if you can look at the transcode log to capture the command it is issuing to ffmpeg, and try running that directly on the command line. Sometimes that gives you a better look at the error ffmpeg is giving.
