UFT/QTP System.InvalidCastException Error

Question

Need some help please. I am trying to execute a UFT test via a vb script through a jenkins pipeline. The test executes and runs fine 3/4 times, on the instance where it doesn't run I get the below warning errors which require the user to press continue to run the test.

"Exception of type: System.InvalidCastException. Source: Northwoods.GoWPF.
