I have noticed that I’m getting a fair number of occasions where playback is just stopping randomly. I am playing media from a Plex server via the Plex Kodi library add on not PM4K. It seems more prevalent on 4K Dolby Vision files.
I have uploaded logs, available https://paste.osmc.tv/wurenulumo The issue happened around 22:31 ish on the 21/05/26.
This isn’t a log set with the debug log level enabled… but there are already enough indications that something went wrong on the Plex server, and the data stream from there cuts out abruptly in the middle.

Maybe you should continue looking for help on the Plex forum.
