The iOS App crashed after scrolling by TouchActions, Action, IOS-Gestures

See original GitHub issue

The problem

The app crashed after scrolling via Appium

Environment

Appium version: 1.21.0
IOS: 14.7.1
Real device or emulator/simulator: real device

Details

I tried few ways to scroll, such as: TouchActions, Actions, IOS-Gestures But the app crashed after scrolling immediately.

This issue does not happen when testing by manual. So, I think the cause is in Appium or WebDriverAgent. Please help me define this cause.

Code To Reproduce Issue [ Good To Have ]

public void scrollToLeftInMenuBar() {
        int heightOfScreen = windowSize.getHeight();
        int widthOfScreen = windowSize.getWidth();
        int anchor = (int) (heightOfScreen * 0.115);
        int startPoint = (int) (widthOfScreen * 0.918);
        int endPoint = (int) (widthOfScreen * 0.0726);

        switch (LoadConfig.getAppiumPlatformName().toLowerCase()){
            case "ios":
                System.out.println("Swipe left in IOS by Actions");
                PointerInput finger = new PointerInput(PointerInput.Kind.TOUCH, "finger");
                Sequence dragNDrop = new Sequence(finger, 1);
                dragNDrop.addAction(finger.createPointerMove(Duration.ofMillis(0),
                        PointerInput.Origin.viewport(), startPoint, anchor));
                dragNDrop.addAction(finger.createPointerDown(PointerInput.MouseButton.LEFT.asArg()));
                dragNDrop.addAction(finger.createPointerMove(Duration.ofMillis(2700),
                        PointerInput.Origin.viewport(), endPoint, anchor));
                dragNDrop.addAction(finger.createPointerUp(PointerInput.MouseButton.LEFT.asArg()));
                mobileDriver().perform(Arrays.asList(dragNDrop));
                break;
            default:
                System.out.println("Swipe left in Android and Web by TouchAction");
                new TouchAction(mobileDriver())
                        .press(PointOption.point(startPoint, anchor))
                        .waitAction(WaitOptions.waitOptions((Duration.ofMillis(TimeoutConstants.SWIPE_WAIT_TIMEOUT))))
                        .moveTo(PointOption.point(endPoint, anchor)).release().perform();
