TrueNAS-12.0-U1 Plex Server Crashes Nightly

I have a Plex Sever I have been running on FreeNas without issues for about 2 years I updated to TrueNas Recently and about 2 weeks ago my Plex started crashing every night I am not sure if it is the version of Plex I am currently using Version 1.21.1.3830 I have rolled it back to older and updated it to newer version. I am trying to look through the logs but not sure what logs to be looking at. I am also currently running TrueNAS-12.0-U1 the crashing didn’t start till about 2 weeks ago But I have been on TrueNAS-12.0-U1 since update was available is anyone else experiencing something like this?
