So I've install libreelec on a rasp4 4Gb it's connected to my emby server via the emby-next-gen plugin and the first viodeo after a reboot always plays flawlessly, starts instantly video quality is superb but sometime after (normally about the 3rd or 4th video) that I'll start a video and it'll get about 30 seconds in then stutter briefly and stop, I can't back out all the remote connections shut down, it's a total hardware lock and I have to unplug the Pi. It doesn't seem to be getting hot (using Argon one case).
Setup is all the latest stable versions as I only installed it yesterday, system is installed on 480Gb SSD using a USB adapter, I'm not getting any errors on the hardware so not sure what could be causing a full lockup like this.
