With the help of alturismo, the issue has been resolved. After setting it to "slave," I restarted Unraid, and Emby started up accordingly. Now it plays normally without needing to restart Emby again. Thank you so much! It seems I still don’t fully understand the meanings of "slave" and "shared"—I’ll have to study them more carefully.

I can basically conclude that the issue is with the youshandefeiyang/allinone Docker container. When it is enabled, it randomly becomes unresponsive (I can't determine whether it's a network disconnection or a system crash, but a reboot restores it). I have disabled it for two weeks now, and the issue has not occurred again.
