Hi! We've been encountering crashes like this in iOS 13 devices. On the stack trace, it appears that the NSError object is expecting a string description but got a different type. I want to confirm if my understanding on the stack trace is right and if not, can anyone help me? Or anyone has encountered the same crash.Crash Key: CoreUI: deallocating _CUIInternalLinkRendition 1855 /System/Library/CoreServices/CoreGlyphs.bundle/Assets.carStack Trace:Fatal Exception: NSInvalidArgumentException 0 CoreFoundation 0x19f82498c __exceptionPreprocess 1 libobjc.A.dylib 0x19f54d0a4 objc_exception_throw 2 CoreFoundation 0x19f72843c -[NSOrderedSet initWithSet:copyItems:] 3 CoreFoundation 0x19f828e08 ___forwarding___ 4 CoreFoundation 0x19f82abec _CF_forwarding_prep_0 5 libswiftCore.dylib 0x1acabf4f0 _bridgeCocoaString(_:) 6 libswiftCore.dylib 0x1acabf6bc String.init(_cocoaString:) 7 libswiftFoundation.dylib 0x1d385458c Error.localizedDescription.getter 8 OjO 0x1046552c4 closure #8 in EnterCreditCardViewController.setObservables() + 199 (EnterCreditCardViewController.swift:199) 9 OjO 0x10467bcec thunk for @escaping @callee_guaranteed (@guaranteed Error?) -> () (<compiler-generated>) 10 RxSwift 0x105a86ae4 closure #1 in ObservableType.subscribe(onNext:onError:onCompleted:onDisposed:) + 65 (ObservableType+Extensions.swift:65) 11 RxSwift 0x105a86ce4 partial apply for closure #1 in ObservableType.subscribe(onNext:onError:onCompleted:onDisposed:) (<compiler-generated>) 12 RxSwift 0x105a395fc AnonymousObserver.onCore(_:) + 22 (AnonymousObserver.swift:22) 13 RxSwift 0x105a89540 ObserverBase.on(_:) + 16 (ObserverBase.swift:16) 14 RxSwift 0x105a896fc protocol witness for ObserverType.on(_:) in conformance ObserverBase<A> (<compiler-generated>) 15 RxSwift 0x105a89b0c partial apply (<compiler-generated>) 16 RxSwift 0x105aa37bc thunk for @escaping @callee_guaranteed (@in_guaranteed Event<A>) -> () (<compiler-generated>) 17 RxSwift 0x105a42b70 BehaviorSubject.on(_:) + 14 (Bag+Rx.swift:14) 18 RxSwift 0x105a43b40 protocol witness for ObserverType.on(_:) in conformance BehaviorSubject<A> (<compiler-generated>) 19 RxSwift 0x105a898a0 ObserverType.onNext(_:) + 30 (ObserverType.swift:30) 20 RxRelay 0x105a201e0 BehaviorRelay.accept(_:) + 20 (BehaviorRelay.swift:20) 21 OjO 0x1045c9b10 closure #2 in CreditCardViewModel.updateUser(ccAccount:) + 60 (CreditCardViewModel.swift:60) 22 RxSwift 0x105a86aa8 closure #1 in ObservableType.subscribe(onNext:onError:onCompleted:onDisposed:) + 68 (ObservableType+Extensions.swift:68) 23 RxSwift 0x105a86ce4 partial apply for closure #1 in ObservableType.subscribe(onNext:onError:onCompleted:onDisposed:) (<compiler-generated>) 24 RxSwift 0x105a395fc AnonymousObserver.onCore(_:) + 22 (AnonymousObserver.swift:22) 25 RxSwift 0x105a895ac ObserverBase.on(_:) + 23 (ObserverBase.swift:23) 26 RxSwift 0x105a896fc protocol witness for ObserverType.on(_:) in conformance ObserverBase<A> (<compiler-generated>) 27 RxSwift 0x105a73fec ErrorProducer.subscribe<A>(_:) + 30 (Error.swift:30) 28 RxSwift 0x105a867dc ObservableType.subscribe(onNext:onError:onCompleted:onDisposed:) + 80 (ObservableType+Extensions.swift:80) 29 OjO 0x1045c9910 CreditCardViewModel.updateUser(ccAccount:) + 55 (CreditCardViewModel.swift:55) 30 OjO 0x1045c9f9c closure #1 in CreditCardViewModel.getToken(cardInfo:) + 78 (CreditCardViewModel.swift:78) 31 OjO 0x1045ca030 thunk for @escaping @callee_guaranteed (@guaranteed CCCAccount?, @guaranteed Error?) -> () (<compiler-generated>) 32 CardConnectConsumerSDK 0x106167638 (Missing) 33 CardConnectConsumerSDK 0x106167e80 (Missing) 34 CFNetwork 0x1a2a3c2cc CFNetServiceBrowserSearchForServices 35 CFNetwork 0x1a2a4c800 _CFHTTPMessageSetResponseProxyURL 36 Foundation 0x19fbe961c __NSBLOCKOPERATION_IS_CALLING_OUT_TO_A_BLOCK__ 37 Foundation 0x19faf33d8 -[NSBlockOperation main] 38 Foundation 0x19fbeb8a4 __NSOPERATION_IS_INVOKING_MAIN__ 39 Foundation 0x19faf3070 -[NSOperation start] 40 Foundation 0x19fbec29c __NSOPERATIONQUEUE_IS_STARTING_AN_OPERATION__ 41 Foundation 0x19fbebd68 __NSOQSchedule_f 42 libdispatch.dylib 0x19f4a481c _dispatch_block_async_invoke2 43 libdispatch.dylib 0x19f4f2184 _dispatch_client_callout 44 libdispatch.dylib 0x19f4a41d0 _dispatch_main_queue_callback_4CF$VARIANT$mp 45 CoreFoundation 0x19f7a23c4 __CFRUNLOOP_IS_SERVICING_THE_MAIN_DISPATCH_QUEUE__ 46 CoreFoundation 0x19f79d3b8 __CFRunLoopRun 47 CoreFoundation 0x19f79c8bc CFRunLoopRunSpecific 48 GraphicsServices 0x1a9608328 GSEventRunModal 49 UIKitCore 0x1a38326d4 UIApplicationMain 50 OjO 0x104583f64 main + 21 (MappableObject.swift:21) 51 libdyld.dylib 0x19f627460 start
