Of course.. no new version of server, how do you expect it to be solved?
Paying for hwtranscode that doesn't work

Sorry, I did not look all the log files.  They are from last year and maybe no longer applies.

All Subtitles in S_HDMV/PGS have to be scanned and converted to text to be ready to be selected.
Picture based subtitle format used on BDs/HD-DVDs

Your problem media has 3 of these, English, Italian and Spanish as well as other subtitles that all need to be available for he user to switch to, as needed.  Converting PGS graphic subtitles is CPU intensive.  I don't even think hardware decoders will do this, but they might.  So, perhaps your CPU is chopped out 10 to 25% just for these subs.

True HD Dolby Atmos is also probably being transcoded.  I am unsure if many setups allow this to pass and directly play.  I think you would need an advanced AV Amp with built in audio coding support for each and the connection probably only works for direct if it is received by either HDMI or digital audio.  Emby normally outputs in TCP/IP over Wifi.  This would mean another transcoding layer.  Transcoding audio might use up another 40% of some CPU's, just a guess

The media video has a bit-rate of 32.4 Mb/s.  This probably also triggers a transcoding to make a lighter weight bitrate for end users to handle, either local or over the Internet which would require again a TCP/IP packet stream.  Very large bitrates online can fail simply because packets may arrive out of order due to Internet traffic and have to be requested a 2nd or multiple times.  The browser or TV app player may have limited cache to handle this out of order packets and will not even present a new media frame until that frame download is complete and probably.  So transcoding a large media file to a lower bitrate might take another 60% on some CPU's to make the scan ahead cached streaming video.

In short, this media file which plays fine on a blu-ray is perhaps too much for your setup.  You can look at individual bit rates and the speed of your network and say that it should be able to handle it.  All the transcoding and converting requests being done at the same time is probably causing your issues.  This full size blu-ray file with all the subtitles would never be made available on commercial video content streaming sites.  It would always be pre-converted down to around 3 Mb/s .mp4 and AAC surround audio.  Your media has not been prepped in this way, so not being able to play, I think, is not really surprising.  Convert the subtitles you want to separate text files.  Remove them from being embedded in the video and pre convert the video to 2.4 to 3 Mb/s on 1080P .mp4 or if you must,  .mkv, which will still need to be converted and loose a generation for maybe 70% of users. Change the audio to AAC surround.

The media will probably play fine for everyone after you do this. Auto transcoding is easier and a nice feature, but you need hardware that can support all the layers and bitrates you throw at it.  I don't think you have hardware that can do that.  This is just a summary guess based on the original media.
