I am using macOS 12.6 Katalon Studio 8.3.0 I have created a GitHub repository that contains a Katalon Studio project where you can reproduce the problem: [image] GitHub - kazurayam/KatalonStudioCanNotRenameKeywordClass Contribute to kazurayam/KatalonStudioCanNotRenameKeywordClass development by creating an account on GitHub. What happend: In this project, I have a Keyword class com.kazurayam.ks.testobject.BiMatcher. BiMatcher class works fine. You can try executing it by running a Test Cases/junit4/com/kazurayam.ks.testobject/BiMatcherTestRunner Also you can run it by Test Suites/junit4/TS1 The test cases work fine. Now, I wanted to renamed the class BiMatcher to BilingualMatcher. I tried to rename it in the Tests Explorer by click the class; click mouse button right; Rename. When I tried it, Katalon Studio hanged for 10 or 20 seconds; then came back. But the BiMatcher class was still BiMatcher. Katalon Studio failed to rename it to BilingualMatcher. I checked the .log file. log.txt (22.2 KB) This contains a Stack Trace message: !ENTRY org.eclipse.e4.ui.workbench 4 0 2023-03-03 22:56:41.621 !MESSAGE !STACK 0

This issue looks similar to another problem: [image] Katalon Studio erased a Test Case code when it was moved, and then renamed Katalon Studio This post follows my previous post: I believe that I have found out a procedure how to reproduce the incident (Test Case code is erased by Katalon Studio). So I would explain it here. I used 2 machine environments. The issue was reproduced on both. MacOS12.6 + Katalon Studio 8.3.0 Windows 10 + Katalon Studio Standard Editon 8.4.1 I did: Create a new Katalon Project Create a new Test Case at Test Cases/sub/subsub/TC1. The code is just skeltal as follows: import com.kms.katalon.cor… Katalon Studio can not rename project entities.
