here is a screenshot of my Transcoder setup in Plex Media server Settings.

here is a screenshot of the error message I receive when trying to play any content in my library.

here is a screenshot of the size of mt /dev/shm

I can confirm setting the transcoding location to /tmp works just fine and playback is working flawlessly there. this is only occurring with /dev/shm trying to achive RAM Transcoding in Plex.

If you have any questions or need any additional information to assist this, please let me know thank you for your time and I look forward to a response.

The setting in Plex for Transcoder temporary directory needs to be /transcode

I use tmpfs in my compose config to create /transcode: Compose file version 3 reference | Docker Documentation

What you have in your compose config is mounting /dev/shm to /transcode inside your container, so setting the Plex option to /dev/shm inside the container is wrong.
