I’m having the same issue after the update which I did about 1 hour ago. As soon as my Nvidia Shield connects it crashes Plex on my Synology NAS. Been working fine until tonight. I can watch on my PC using Chrome browser without issues.
Plex server 1.21.1.3876
Plex app version on shield, can’t tell but it’s updated to the latest.
App on Android phones will also crash the server. App is updated to latest on my phone. App version is 8.11.0.22186
I’ve uninstalled and re-installed plex and the issue still exists if I use my Android phone or Nvidia. I can’t watch anything right now. I rolled back tp 1.21.1.3842 and the issue went away. There is something really screwy with the latest version.
I didn’t touch the nvidia app or android app. I did the reinstall of the older version and that was all. No reboots or anything else, it just started working again.
As I noted in the other issue tracking this one, deleting/re-adding users didn’t work for me (just created a massive headache to get the invites all re-accepted), and I eventually downgraded to fix the problem.
That’s obviously not tenable for security reasons, so it’d be great to get a confirmation of the real problem and an official fix.
