Hi, I have a similar problem.
I run my test in Azure DevOps pipeline with KRE lisence. I can run the tests with Katalon 7.5.5 but cannot run with upper than 7.6. (also latest 7.8.0). I got same error as @liam.by. It just said Unable to execute test suite 'Test Suites/Test sute name'
I can run the tests locally with Katalon studio 7.8.0.
@liam.by Do you get any solution or find the cause?
