There is a crash that is occurring in `DB::close_internal()` when a Dart app is being torn down because the Logger instance has already been destroyed when the `PersistedSyncMetadataManager` is destroyed. It only happens if the debug level is set to something higher than `info`.
The issue is here: https://github.com/realm/realm-core/blob/master/src/realm/db.cpp#L2045-L2046
From slack conversation: https://mongodb.slack.com/archives/C010R3CMP3N/p1723112587976859
Does this ring a bell? Happens consistently on process exit when setting trace level to something finer than INFO in a test using realm-core 14.11.0.

This is a minimal reproduction:
import 'package:realm_dart/realm.dart'; void main(List<String> arguments) async { Realm.logger.setLogLevel(LogLevel.trace); final app = App(AppConfiguration('dummy')); // following throws since app doesn't exist, // but notice the crash on exit final user = await app.logIn(Credentials.anonymous()); }
