Hello everyone, I’m having an error that I can’t run my test case in the following case: I can only run it once. When I open Katalon, after that run, I get an error like the following image.  
I use imac mini m1. Macos version 12

@duongpd1  
Are you using any data for the test cases from Excel File?
