On my end it is easily reproducible. It only crashes when trying to connect to the network. And no, I can not connect to the network, even when it does not crash. This problem is nonexistent in Raspbian, implying it is a software issue.
Does LibreELEC do vnc? I can privately give you ssh, if you want to explore and reproduce the issue yourself. Unfortunately I do not have a second Pi or sd card to absolutely verify this is a software issue.
MIne has the video files in network and I use userdata.xml to point to a mysql database and crasching after 5 minutes of use is simple unusable waiting for another build patiently
