Description

Hello, we've updated realm-swift from v10.49.2 to v10.52.1, and our users now encounter a new crash during application start. It's reported as N5realm18MultipleSyncAgentsE. It seems similar to this one we've also seen on realm-kotlin: https://github.com/realm/realm-kotlin/issues/1781
Here's a simplified version of our startup code:

var config = getRealmConfig()
DispatchQueue.global(qos: .userInitiated).async {
    var error: Error?
    // I've tried to add this autorelease pool to force this background realm to close before we start working with it from the UI
    autoreleasepool {
        do {
            let realm = try RLMRealm(configuration: config)
            TrackDataManager.manager.importNewTracks(realm)
        } catch let realmError {
            error = realmError
            // report error
        }
    }
    
    DispatchQueue.main.async {
        RLMRealmConfiguration.setDefault(config)
        // Now we're ready to init app UI.
        completion(error)
    }
}

Sometimes it takes some time to open Realm for the first time during app startup, which is why we've moved initialization to a background queue. Once it's finished, we initialize the app UI.
I believe that this crash happens because one instance of RLMRealm is being deleted and another one opens the same database at the same time.
