I don’t trust the “in-app update” function. I know many people encountered oddities due to the “in-app update”.

See [Update Katalon Studio | Katalon Docs](https://docs.katalon.com/katalon-studio/get-started/workspace-settings/update-katalon-studio)

It is quite likely that the “in-app update” causes problems in more cases (not listed in the doc). You should avoid it.

Please try removing the current Katalon Studio installation from disk, and reinstall it cleanly
