As the crash seems desktop related I see no logcenter acivities.
Seems to be working fine on my iMac after updating to macOS 11.6, running Plex for Mac 1.35.1.
Maybe you want to upgrade the version of Plex for Mac before further troubleshooting?
The same probably goes for the server version (not sure which you got installed as you’re listing both 1.18.5 and 1.24.1 – the latest public release is version 1.24.3).
Go to Plex download pages, at the bottom of this page.
Download the latest player and/or server. Player can be installed on your computer.
the spk has to be installed in/or your server. I have Synology, I go to Package center and at the top of page you will find manual install field. I am no pro but it is easy. Good luck
