HW transcoding broken w/ v550 NVIDIA drivers (binhex-plex v1.40.1.8227, Linux 6.1.64-Unraid, GTX960)

Server Version#: v1.40.1.8227
Player Version#: Any

Hardware transcoding is broken for kernel version Linux 6.1.64-Unraid, with an NVIDIA GTX960 passed through to the binhex-plex docker version of unraid server v1.40.1.8227 (w/ plex pass) using v550 series NVIDIA drivers. Rolling back to v545 series drivers fixes it.

Some relevant log lines seem to be:

TPU: hardware transcoding: enabled, but no hardware decode accelerator found
...
TPU: hardware transcoding: final decoder: , final encoder: 
...
Transcode runner appears to have died.

nvidia-smi shows card as detected, Plex shows it as my current HW transcode option. nvidia-smi briefly shows the plex transcode process starts running when a transcode is requested, and then it, indeed, immediately dies.

I have tried transcoding both to disk and memory (with software transcoding verifying that I have no problems writing to those locations). Failed HW transcoding does not fall back to software transcoding. The client just sits waiting for chunks that constantly 404.

Here is a full log of an attempted transcode session
