I just installed the new version of LibreELEC (beta 2023.01) on my Odroid C2 SBC and I noticed that the HEIF addon does not work. As soon as I enable it and I want to open a folder that contains HEIF images, LibreELEC auto-reboots. I cannot find a way to make logs or whatever, but it seems a pretty serious bug when it auto reboots with no error or information. The user accessible log functionality only shows that the system started correctly.
If you need any more information please let me know.
