Was using LMS 8.2 on a Mac mini running Mojave.
Upgraded to Monterey.

Now my media folder location has disappeared, and I can't type anything or hit the "+" in LMS Preferences to re-add the media folder.
Almost all of the options in the preferences tabs are greyed out.

Start the server; it quickly stops. Can't view the logs.

If I look at the server.pref file it has the correct location of the media folder, which is on an external drive and which did not change during the OS upgrade.

Tried to install 8.3; same result.

Probably need to nuke preferences, but not sure how to do that. if I delete server.pref, the library name goes away in system preferences, but I still can't enter anything new.
