met the same issue, any body can help?

I met the same question，and i found it maybe related to the function calling ---- "window.webkit.messageHandlers.CustomName.postMessages", if i deleted those methods, it maybe becomes correct。 it really confused！ sometimes we delete some common JavaScript， it can become correct too! SAD !!!!!

I met the same questions, hope workaround . and by the way ,we met another wkwebview's crash On iOS14.0. the crash thread info like below: 1 libobjc.A.dylib objcrootReleaseWasZero (in libobjc.A.dylib) + 72 2 UIKitCore[UIFocusContainerGuideMapEntry setFocusContainmentFrame:] (in UIKitCore) + 16 3 UIKitCore[UIFocusRegionMapEntry mapEntriesByOccludingWithFrame:] (in UIKitCore) + 344 4 UIKitCore[UIFocusRegionMapSnapshot .cxxdestruct] (in UIKitCore) + 96 5 UIKitCore[UIFocusableRegionMapEntry description] (in UIKitCore) + 116 6 UIKitCore[UIFocusableRegionMapEntry description] (in UIKitCore) + 228 7 UIKitCore[UIFocusRegionMapSnapshot visualRepresentationWithMinimumArea:] (in UIKitCore) + 1844 8 UIKitCore[UIFocusRegionMapSnapshot visualRepresentationWithMinimumArea:] (in UIKitCore) + 672 9 UIKitCore[UIFocusRegionMapSnapshot snapshotByFulfillingPromiseFocusRegionEntry:] (in UIKitCore) + 848 10 UIKitCore[UIStateMachine(Legacy) setStaticTransitionFromState:withEvent:toState:] (in UIKitCore) + 128 11 UIKitCore[UIEstimatedTouchRecord initWithLiveTouch:freezeTouch:contextID:] (in UIKitCore) + 4 12 UIKitCore[UIWebDocumentView(Interaction) deepestNodeAtViewportLocation:] (in UIKitCore) + 96 13 WebKit[WKProcessAssertionBackgroundTaskManager updateBackgroundTask] (in WebKit) + 272 14 WebKit bool IPC::MessageSender::send<Messages::WebPaymentCoordinator::DidAuthorizePayment>(Messages::WebPaymentCoordinator::DidAuthorizePayment const&, unsigned long long, WTF::OptionSet<IPC::SendOption>) (in WebKit) + 28 15 WebKit[WKContentView(WKInteractionPreview) presentedViewControllerForPreviewItemController:] (in WebKit) + 1564 16 UIKitCore[UIBezierPath encodeWithCoder:] (in UIKitCore) + 140 17 UIKitCore 21+[UIColor blackColor]blockinvoke (in UIKitCore) + 140 18 UIKitCore[UIDisplayP3Color initWithDisplayP3Red:green:blue:alpha:] (in UIKitCore) + 196 19 UIKitCore[UIDeviceRGBColor set] (in UIKitCore) + 48 20 UIKitCore 83+[UIAppearance applyInvocationsTo:window:matchingSelector:onlySystemInvocations:]blockinvoke (in UIKitCore) + 312 21 UIKitCore[UIAppearance appearancesAtNode:withObject:] (in UIKitCore) + 992 22 UIKitCore _processEventQueue (in UIKitCore) + 8700 23 UIKitCore UIDrawViewRectAfterCommit (in UIKitCore) + 708 24 UIKitCore[UIStatusBarLockView animateUnlockWithCompletionBlock:] (in UIKitCore) + 704 25 UIKitCore[UIStatusBarDualCellularSignalView setTopConstraint:] (in UIKitCore) + 0 26 CoreFoundation[_NSDictionary0 copy] (in CoreFoundation) + 0 27 CoreFoundation copyhelperblocke832o40o48b56o64r (in CoreFoundation) + 16 28 CoreFoundation destroyhelperblocke832o40o48b56r64r (in CoreFoundation) + 16 29 CoreFoundation CFRunLoopTimerSetNextFireDate (in CoreFoundation) + 1072 30 CoreFoundation CFRunLoopTimerCreate (in CoreFoundation) + 384 31 GraphicsServices GSSendEvent (in GraphicsServices) + 252 32 UIKitCore[UISearchControllerATVSearchBarAnimator updateLayoutForGridKeyboard:animated:] (in UIKitCore) + 4092 33 UIKitCore[_UISearchFormSheetPresentationController presentationTransitionWillBegin] (in UIKitCore) + 20 34 JD4iPhone main (in JD4iPhone) (main.m:15) 35 libdyld.dylib 0x00000001802bb3d4 (in libdyld.dylib) Hope Reply from Apple and workaround!!!!!!
