Video Optimization feature is not working

Server Version#: 1.25.8.5663
Player Version#: 4.69.1

Running Snap Plex Media Server Version 1.25.8.566 on Ubuntu 22.04
I am trying to get the Version Optimization to work but I keep getting a vague unclear error:

unable to convert

My media library is located on

/media/libraries/

Due to limited space on my main SSD, I moved the ‘Plex Media Server’ folder to a different location on its own SSD:

/media/plex/

using the following:

sudo cp -a /var/snap/plexmediaserver/common/Library/'Application Support'/'Plex Media Server'/. /media/plex/'Plex Media Server'

sudo rm -rf /var/snap/plexmediaserver/common/Library/'Application Support'/'Plex Media Server'

sudo ln -s /media/plex/'Plex Media Server' /var/snap/plexmediaserver/common/Library/'Application Support'/

This seem to work just fine and I am not getting any errors after doing that.
I also created the Directory

/media/Plex/optimized/

with a subfolder for each of the libraries and I set the ownership to root and adjusted permissions to rwx so Snap Plex can read and write to those directories. That solved the error of ¨unable to write to disk¨ when using this directory to save the optimized versions.

The console tap in Plex is showing me an error when trying to optimize a video (no option is seleced):

[Transcoder] Unrecognized option ‘crf:0’.
[Transcoder] Error splitting the argument list: Option not found

when enabling Use hardware-accelerated video encoding I get this Error:

[Transcoder] Unrecognized option ‘crf:0’.
Jobs: ‘/snap/plexmediaserver/268/Plex Transcoder’ exit code for process 19902 is 1 (failure)

and when enabling Use hardware acceleration when available I get:

[FFMPEG] - OpenEncodeSessionEx failed: unsupported device (2): (no details)

Has anyone been in a similar situation? Your help is much appreciated.

I took the easy way out of this and migrated from Snap to apt version of PMS… now things work as expected
