This is caused by disk space issues (https://github.com/woocommerce/woocommerce-ios/issues/3246). But this just goes to show that we should really not crash the app if saveIfNeeded fails.

I'm not sure if is related, but this last one comes with logs attached at the same time of the crash pointing to a Networking error and to a deprecated endpoint for shipping:

2022/08/08 13:02:39:383  ⚠️ You are using an older version of the Woo REST API: wc/v2, for path: orders/10206/shipment-trackings/
2022/08/08 13:02:40:400  🔵 Tracked order_notes_loaded
2022/08/08 13:02:41:178  ⛔️ Error synchronizing tracking: L’opération n’a pas pu s’achever. (Networking.DotcomError erreur 5.)
2022/08/08 13:02:41:202  Order 10206 not eligible for shipping label creation: store_not_eligible

While we log this error via DDLog on checkCreationEligibility() and we do not crash the app at this point, I wonder if could be related to attempting to do a CRUD operation before we get the callback from the ShippingLabelRemote: We call .saveIfNeeded() 4 times in ShipmentStore involving storage and a shipping label and try to save this data if has changed:

• upsertTrackingProviderData
• deleteStoredShipment
• addStoredShipment
• addCustomStoredShipment

The NSManagedObjectContext+Storage:

    /// Persists the changes (if any) to disk.
    ///
    public func saveIfNeeded() {
        guard hasChanges else {
            return
        }

        do {
            try save()
        } catch {
            let nserror = error as NSError
            logErrorAndExit("Unresolved error \(nserror), \(nserror.userInfo)")
        }
    }
