Issue Solved – Big Thanks to the Katalon Community! 
Hi @kazurayam @dineshh
Thank you for sharing your solutions with me!
I was facing the UnsupportedClassVersionError (class file version 65.0 vs 61.0), and it had me stuck for a while. Thanks to the helpful suggestions and support from the Katalon Community, I was able to identify the problem with the JAR compatibility and resolve it by using Java 17-supported libraries.
Really appreciate the guidance and quick responses. It’s great to be part of such a responsive and knowledgeable group. Looking forward to learning more and contributing back!
