This happens for me and its a big problem! All movies fail when using subtitles and some work without them and the rest also fails without subtitles. Conversion failed. transcoder crashed or failed to start up.
Logs please - there could be many different reasons for the transcoder to report an error.
Please enable debug logging on the server (it should be on by default)
See https://support.plex.tv/hc/en-us/articles/201643703-Reporting-issues-with-Plex-Media-Server
Restart the server to get fresh logs
Then try one with subtitles that fails - note down the time and the error and the video title
Then try one without subtitles that fails - note down the time and the error and the video title
Then capture the logs
See https://support.plex.tv/hc/en-us/articles/200250417-Plex-Media-Server-Log-Files
Attach the logs plus details of the two tests and times/ titles
