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:

> **[GitHub - kazurayam/KatalonStudioCanNotRenameKeywordClass](https://github.com/kazurayam/KatalonStudioCanNotRenameKeywordClass)**

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.

This contains a Stack Trace message:

This issue looks similar to another problem:

> [@Katalon Studio erased a Test Case code when it was moved, and then renamed](http://forum.katalon.com/t/katalon-studio-erased-a-test-case-code-when-it-was-moved-and-then-renamed/84169):

> 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.
