Plex crash after starting. Transcoder error in log

Server Version#: 1.24.1.4931
Player Version#:iOS 7.22

Mac mini
MacOS 2.3 Ghz quad-core
16GB of memory

Plex library on Synology

HDHomeRun Quad

Our Plex Server keeps crashing and need some help narrowing down what is causing this. We have been using PMS for years, it has been very solid so I haven’t had to do much troubleshooting over the years, but in the last month it has started crashing after a few minutes of running. We are using an older Mac mini that is dedicated to Plex Server. The normal things to check appear fine, plenty of free space (800 GB), plenty of free CPU cycles & memory, NAS not going to sleep, etc.

If need be, I can punt then reinstall Plex fresh, but like to understand why this happening to better troubleshoot Plex in the future. I have looked through the forum, the answer is probably out here, but I must be missing it, apology.

I see this before the crash
