Transcoder crash with audio tracks "TRUEHD 7.1"

Server Version#: 1.41.3.9314 (running on truenas using the plex pass image)
Player Version#: updated Plex for LG 5.90.1 (client) 9.2.1 (platform)

Every times I play a movie for which the audio track is “TRUEHD 7.1” the transcoder crashes.
The TV does not support DTS audio (if I enable in the client setting I do not hear anything) and because of that the transcoder for audio (video is direct play) starts. I got a transcoding to “EAC3” but is seems that also disabling this format in the client does not fix the issue.

That seems a bug in the transcoder.
Here the errors I get and a truncated log file from when the issue happens:

That happens with almost all movies that have “TRUEHD 7.1” track.
Could you provide some feedback and possibly a fix ?

Thanks!

This bug seems quite severe… how is possible nobody looks into it ?
