Error while starting direct play on everything after update

[sk1036]

Hi,

Running Ubuntu 24.04.1
Jellyfin installed 'bare', no docker.
Just updated to 10.10 from 10.9.11 (I think)
I do have hardware transcode enabled, seems to work. Issue persists if I turn it off (CPU struggles though!)
I also have a reverse proxy, but this issue exists locally so don't think that's an issue.
The device I tend to use is LG using webOS app. Streaming from my phone also appears to have the same issue.

Previously I could stream to a device in my local network and as long as the file was suitable it would direct play all as expected.
Now, every.single.file seems to take an age to start playing and when it does start the playback info indicates it is transcoding.
As the title suggests; the reason is given as 'Error while starting direct play'.
Once files are playing it seems fine, except I lose and HDR/dovi on account of the transcode.

I think I've got the pertinent points from logs below but either I am missing something or they're not being helpful. 
I don't know how to troubleshoot this further or maybe there's a nugget in the below logs.
Any kind soul willing to part some wisdom has my gratitude!
