SWT Exception When trying to capture Objects iOS

Katalon throws SWT Exception when trying to spy mobile on iOS. Objects with tree hierarchy mostly.
It does not run the test case as well. The application freezes when trying to capture the objects or run the test cases ending up in throwing SWTException.

Katalon version 7.2.1
Appium Version 1.16.0
Xcode version 11.3.1

Thanks in Advance
