Steps & Code to Reproduce

This is our Libre3 app. Looks like it happens when we call:

func purgeRecordsBefore<T>(entityClass: T.Type, realm: Realm, earliestToKeepUTC: Int64) where T: RealmSwift.Object {
    // Log.v("Delete data before : \(earliestToKeepUTC)")
    realm.delete(realm
        .objects(entityClass)
        .filter("_timestampUTC<%@", earliestToKeepUTC))
}

Hi! Thanks for reporting the crash. This issue existed for quite a while in realm core, and it was very difficult to track it down unfortunately.

It's fixed by #6962 and released with realm core v13.20.1. You would need to update swift sdk for your app. It is fixed since swift sdk v10.42.2.

Please, reopen if you still experience this issues after an update.
