console log take from the iphone device

We have a Hybrid mobile application. on iOS 12, we are using WKWebView. I minimise the application so that it goes in the background. I wait for the screen to lock and the application is suspended. Now, I unlock the application and tap on the application icon and bring it to the foreground. The app does not respond to the user action - e.g. tap. When I look at the log, I see the following message: check the attachment image1.png

To recover, I lock the device and unlock it (while the application is still in foreground). The application recovers and starts responding. In this case, I see the following messages in the log: check the attachment image2.png

I tried searching but could not find a related issue. Kindly suggest if I need to look into something specific. Would appreciate all the help as this is impacting our customers.
