Error: Unbalanced calls to begin/end appearance transitions for <UIViewController: 0x7f9262f09330>

Dear All,
i using moe 1.2.5, libgdx 1.9.6-SNAPSHOT, link admob framework.
Interstitial had showed. But got error.
And the error is: ios-moe[2263:113692] Unbalanced calls to begin/end appearance transitions for <UIViewController: 0x7f9262f09330>.

My code:

public void F_ShowInterstitial() {
    try {
        if (interstitial != null && interstitial.isReady()) {
            long time_temp = System.currentTimeMillis();
            if (interstitial_TimeLastShow == 0
                    || time_temp - interstitial_TimeLastShow > 5 * 1000 * 60) {
                interstitial_TimeLastShow = time_temp;

                if (rootViewController == null) {
                    rootViewController = UIViewController.alloc().init();
                }
                if (interstitialWindow == null) {
                    interstitialWindow = UIWindow.alloc().initWithFrame(UIScreen.mainScreen().bounds());
                    interstitialWindow.setRootViewController(rootViewController);
                }
                interstitialWindow.setHidden(false);
                interstitialWindow.makeKeyAndVisible();
                interstitial.presentFromRootViewController(rootViewController);
                
            } else {
                f_interstitialcallback();
            }
        } else {
            f_interstitialcallback();
        }
    } catch (Exception e) {
        f_interstitialcallback();
    }
}

Please help!
Thanks!
