Samsung TV Plex always stops before end of movie/programme

I’ve also this problem. Before it was working fine when I left EarlyAccess on my TV app. Now I noticed that this is not an option anymore as the app updated. Most shows I’m watching ending at the last scene with “an unexpected playback problem occurred”.
Server version doesn’t matter here, it was happening to me from when the new “Early access” app was introduced.
Anyone can help here?

The OK button is not clickable, I need to force close Plex app to start using Plex again.
