Not at all sure what's going on here. CentralAuthDatabaseManager gets the $options object via MediaWiki's service container, and the wiring defines it's always going to be a ServiceOptions object and nothing else (even if the MainConfig service was overridden), and the call stack shows CentralAuthUtils which always gets CentralAuthDatabaseManager via the service container. I am tempted to close this unless we see it happening more than once.

Agreed. Most likely opcache corruption. Affected only 1 host with an unexplainable error that would naturally be easy to reproduce if it wasn't an opcache error, and recovered on its own and is no longer reproducible without code changes.
