Thanks for reporting this. The crash has been already fixed, see details at:
opened 05:23PM - 08 Jan 24 UTC
closed 11:16PM - 08 Jan 24 UTC
## Summary
When the language is set to **Simplified Chinese** in **Utilities\La… nguage Tools**, the program cannot be opened after restarting, and the Windows problem report shows that `SlicerApp-real.exe` has stopped working. Switching to **Japanese** will display Japanese normally, switching to **Traditional Chinese** will display English, but it can start normally.
After careful investigation, after deleting the **Slicer_zh-CN.qm** file in the `%LocalAppData%\slicer.org\Slicer 5.6.1\bin\translations` directory, the program can start normally.
## Steps to reproduce
1. Press Ctrl+4, enter **Extensions Manger**, search for "language", you can see a utility called **LanguagePacks**, restart the software after installation
2. Press Ctrl+2, open **Application Setting**, check **internationalization**, and restart the software.
3. Click **Utilities**→**Language Tools** in the module options, select **Weblate** in the Input translations column, click the **refresh** button, you can see a list of many languages, check **Japanese**, **Simplified Chinese** and **Traditional Chinese**, click **Update translation files** , the translation file will start to download automatically. After downloading, restart the software
4. Open **Language Tools** again, select **Application language** as **Chinese (China)** at the top, click **Restart the application** on the right, and the software will restart.
5. When starting the software, text such as the initialization module will be displayed, but when it reaches the `Loading module "SegmentEditor"... `stage, it will crash.
6. Also select the **second** Chinese (China). After restarting, the software can be started normally but it is displayed in **English**.
7. After selecting **Japanese**, the software starts normally and the translation takes effect.

In summary, the problem is caused by incorrect translation of Segmentations module: it is translated as Segmentation, which is the exact same word that is used as module category name.
We fixed the crash in the Slicer Preview Release so that now a warning is logged instead of crash when a module name matches a module category name. However, you still need to modify the Chinese translation to not use the same string as both a module name and a module category name.
