I haven't the slightest clue what could have caused this, but after restarting my Mac last night, I was presented with a 'Quick Start' screen that asked me to choose a language for Emby & essentially start configuring the application from scratch. All of my libraries, plugins, and settings have completely vanished. I have my HD regularly backed up with Time Machine, so I am hoping there is a way to revert & restore, but I'm not sure where to begin. I'm hoping to figure out the cause before I get started so I can be sure to avoid whatever it was that contributed to this outcome, but the most important thing is restoring the account without having to manually set everything up again.
Any guidance appreciated.
