Hey there, I wonder if you have still the same problem. I bought the new NVIDIA Shield TV 2019 and updated the Plex app as soon as I got the device up and running. Plex crashes after around 10min of 4k playback. The video starts pausing just before Plex crashes and pressing the control buttons doesn’t trigger any action, it seems like an Out of Memory error to me, most likely the new Plex app as a memory leak.
